This pull request refactors the genesis setup function, the major
changes are highlighted here:
**(a) Triedb is opened in verkle mode if `EnableVerkleAtGenesis` is
configured in chainConfig or the database has been initialized previously with
`EnableVerkleAtGenesis` configured**.
A new config field `EnableVerkleAtGenesis` has been added in the
chainConfig. This field must be configured with True if Geth wants to initialize
the genesis in Verkle mode.
In the verkle devnet-7, the verkle transition is activated at genesis.
Therefore, the verkle rules should be used since the genesis. In production
networks (mainnet and public testnets), verkle activation always occurs after
the genesis block. Therefore, this flag is only made for devnet and should be
deprecated later. Besides, verkle transition at non-genesis block hasn't been
implemented yet, it should be done in the following PRs.
**(b) The genesis initialization condition has been simplified**
There is a special mode supported by the Geth is that: Geth can be
initialized with an existing chain segment, which can fasten the node sync
process by retaining the chain freezer folder.
Originally, if the triedb is regarded as uninitialized and the genesis block can
be found in the chain freezer, the genesis block along with genesis state will be
committed. This condition has been simplified to checking the presence of chain
config in key-value store. The existence of chain config can represent the genesis
has been committed.
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 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.
