Since Go 1.22 has deprecated certain elliptic curve operations, this PR removes
references to the affected functions and replaces them with a custom implementation
in package crypto. This causes backwards-incompatible changes in some places.

* accounts/scwallet: use go-ethereum crypto instead of go-ecdh
github.com/wsddn/go-ecdh is a wrapper package for ECDH functionality
with any elliptic curve.
Since 'generic' ECDH is not required in accounts/scwallet (the curve is
always secp256k1), we can just use the standard library functionality
and our own crypto libraries to perform ECDH and save a dependency.
