This commit makes it so that the struct logger will not emit logs while
system calls are being executed. This will make it consistent with
the JSON and MD loggers. It is as it stands hard to distinguish when
system calls are being processed vs when a tx is being processed.

This PR implements EIP-7702: "Set EOA account code".
Specification: https://eips.ethereum.org/EIPS/eip-7702
> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.

This PR attempts to clean up some ambiguities and quirks from recent
changes to evm flag handling.
This PR mainly focuses on `evm run` subcommand, to use the same flags
for configuring tracing/output options as `statetest/blocktest` does.
Additionally, it adds quite a lot of tests for expected outputs of the
various subcommands, to avoid accidental changes.

This PR refactors the structlog a bit, making it so that it can be used
in a streaming mode.
-------------
OBS: this PR makes a change in the input `config` config, the third
input-parem field to `debug.traceCall`. Previously, seteting it to e.g.
` {"enableMemory": true, "limit": 1024}` would mean that the response
was limited to `1024` items. Since an 'item' may include both memory and
storage, the actual size of the response was undertermined.
After this change, the response will be limited to `1024` __`bytes`__
(or thereabouts).
-----------
The commandline usage of structlog now uses the streaming mode, leaving
the non-streaming mode of operation for the eth_Call.
There are two benefits of streaming mode
1. Not have to maintain a long list of operations,
2. Not have to duplicate / n-plicate data, e.g. memory / stack /
returndata so that each entry has their own private slice.

When a tx/block was being traced through the API the state hooks weren't
being called as they should. This is due to #30745 moving the hooked
statedb one level up in the state processor. This PR fixes that.

This change relocates the EVM tx context switching to the ApplyMessage function.
With this change, we can remove a lot of EVM.SetTxContext calls before
message execution.
### Tracing API changes
- This PR replaces the `GasPrice` field of the `VMContext` struct with
`BaseFee`. Users may instead take the effective gas price from
`tx.EffectiveGasTipValue(env.BaseFee)`.

This PR improves the output of the markdown logger a bit.
- Remove `RStack` field,
- Move `Stack` last, since it may have very large vertical expansion
- Make the pre- and post-exec metadata structured into a bullet-list
This pull request refactors the EVM constructor by removing the
TxContext parameter.
The EVM object is frequently overused. Ideally, only a single EVM
instance should be created and reused throughout the entire state
transition of a block, with the transaction context switched as needed
by calling evm.SetTxContext.
Unfortunately, in some parts of the code, the EVM object is repeatedly
created, resulting in unnecessary complexity. This pull request is the
first step towards gradually improving and simplifying this setup.

This PR fixes some issues with benchmarks
- [x] Removes log output from a log-test
- [x] Avoids a `nil`-defer in `triedb/pathdb`
- [x] Fixes some crashes re tracers
- [x] Refactors a very resource-expensive benchmark for blobpol.
**NOTE**: this rewrite touches live production code (a little bit), as
it makes the validator-function used by the blobpool configurable.
- [x] Switch some benches over to use pebble over leveldb
- [x] reduce mem overhead in the setup-phase of some tests
- [x] Marks some tests with a long setup-phase to be skipped if `-short`
is specified (where long is on the order of tens of seconds). Ideally,
in my opinion, one should be able to run with `-benchtime 10ms -short`
and sanity-check all tests very quickly.
- [x] Drops some metrics-bechmark which times the speed of `copy`.

When using the prestateTracer, in some cases users are only concerned
with balances or nonce information, and are not interested in the lengthy
contract code or storage data.
Therefore, this PR introduces two new configuration options in the
`prestateTracerConfig` structure:
- `disableCode`
- `disableStorage`
These options allow users to control whether the tracer returns contract
code and storage data during execution tracing. By setting these
options, users can more flexibly customize their needs and focus on
obtaining information that is more critical and relevant to their
specific use cases.
These options work with the default mode as well as `diffMode: true`.

rebased https://github.com/ethereum/go-ethereum/pull/29766 . The
downstream branch appears to have been deleted and I don't have perms to
push to that fork.
`TerminalTotalDifficultyPassed` is removed. `TerminalTotalDifficulty`
must now be non-nil, and it is expected that networks are already
merged: we can only import PoW/Clique chains, not produce blocks on
them.

This PR moves the logging/tracing-facilities out of `*state.StateDB`,
in to a wrapping struct which implements `vm.StateDB` instead.
In most places, it is a pretty straight-forward change:
- First, hoisting the invocations from state objects up to the statedb.
- Then making the mutation-methods simply return the previous value, so
that the external logging layer could log everything.
Some internal code uses the direct object-accessors to mutate the state,
particularly in testing and in setting up state overrides, which means
that these changes are unobservable for the hooked layer. Thus, configuring
the overrides are not necessarily part of the API we want to publish.
The trickiest part about the layering is that when the selfdestructs are
finally deleted during `Finalise`, there's the possibility that someone
sent some ether to it, which is burnt at that point, and thus needs to
be logged. The hooked layer reaches into the inner layer to figure out
these events.
In package `vm`, the conversion from `state.StateDB + hooks` into a
hooked `vm.StateDB` is performed where needed.

While looking at some mem profiles from `evm` runs, I noticed that
`goja` compilation of the bigint library was present. The bigint library
compilation happens in a package `init`, whenever the package
`eth/tracers/js` is loaded. This PR changes it to load lazily when
needed.
It becomes slightly faster with this change, and slightly less alloc:y.
Non-scientific benchmark with 100 executions:
```
time for i in {1..100}; do ./evm --code 6040 run; done;
```
current `master`:
```
real 0m6.634s
user 0m5.213s
sys 0m2.277s
```
Without compiling bigint
```
real 0m5.802s
user 0m4.191s
sys 0m1.965s
```
Breaking changes:
- The ChainConfig was exposed to tracers via VMContext passed in
`OnTxStart`. This is unnecessary specially looking through the lens of
live tracers as chain config remains the same throughout the lifetime of
the program. It was there so that native API-invoked tracers could
access it. So instead we moved it to the constructor of API tracers.
Non-breaking:
- Change the default config of the tracers to be `{}` instead of nil.
This way an extra nil check can be avoided.
Refactoring:
- Rename `supply` struct to `supplyTracer`.
- Un-export some hook definitions.
Changelog: https://golangci-lint.run/product/changelog/#1610
Removes `exportloopref` (no longer needed), replaces it with
`copyloopvar` which is basically the opposite.
Also adds:
- `durationcheck`
- `gocheckcompilerdirectives`
- `reassign`
- `mirror`
- `tenv`

This is a successor PR to #25743. This PR is based on a new iteration of
the spec: https://github.com/ethereum/execution-apis/pull/484.
`eth_multicall` takes in a list of blocks, each optionally overriding
fields like number, timestamp, etc. of a base block. Each block can
include calls. At each block users can override the state. There are
extra features, such as:
- Include ether transfers as part of the logs
- Overriding precompile codes with evm bytecode
- Redirecting accounts to another address
## Breaking changes
This PR includes the following breaking changes:
- Block override fields of eth_call and debug_traceCall have had the
following fields renamed
- `coinbase` -> `feeRecipient`
- `random` -> `prevRandao`
- `baseFee` -> `baseFeePerGas`

This PR changes how sidechains are handled.
Before the merge, it was possible to import a chain with lower td and not set it as canonical. After the merge, we expect every chain that we get via InsertChain to be canonical. Non-canonical blocks can still be inserted
with InsertBlockWIthoutSetHead.
If during the InsertChain, the existing chain is not canonical anymore, we mark it as a sidechain and send the SideChainEvents normally.
Make tracers more robust by handling `nil` receipt as input.
Also pass in a receipt with gas used in the state test runner.
Closes https://github.com/ethereum/go-ethereum/issues/30117.

Add coinbase address to javascript tracer context.
This PR adds the `coinbase` address to `jsTracer.ctx`, allowing access
to the coinbase address (fee receipient) in custom JavaScript tracers.
Example usage:
```javascript
result: function(ctx) {
return toAddress(ctx.coinbase);
}
```
This change enables custom tracers to access coinbase address,
previously unavailable, enhancing their capabilities to match built-in
tracers.
Introduces the first built-in live tracer. The supply tracer tracks ETH supply changes across blocks
and writes the output to disk. This will need to be enabled through CLI using the `--vmtrace supply` flag.

The beacon root when applied in `state_processor.go` is performed right before executing transaction. That means that contract reliying on this value would query the same value found in the block header.
In that spirit, it means that any tracing/operation relying on state data which touches transaction must have updated the beacon root before any transaction processing.
