This pull request ports some changes from the main state snapshot integration one, specifically introducing the flat state tracking in pathdb. Note, the tracked flat state changes are only held in memory and won't be persisted in the disk. Meanwhile, the correspoding state retrieval in persistent state is also not supported yet. The states management in disk is more complicated and will be implemented in a separate pull request. Part 1: https://github.com/ethereum/go-ethereum/pull/30752
