This PR makes 2 changes to how
[EIP-7825](https://github.com/ethereum/go-ethereum/pull/31824) behaves.
When `eth_estimateGas` or `eth_createAccessList` is called without any
gas limit in the payload, geth will choose the block's gas limit or the
`RPCGasCap`, which can be larger than the `maxTxGas`.
When this happens for `estimateGas`, the gas estimation just errors out
and ends, when it should continue doing binary search to find the lowest
possible gas limit.
This PR will:
- Add a check to see if `hi` is larger than `maxTxGas` and cap it to
`maxTxGas` if it's larger. And add a special case handling for gas
estimation execute when it errs with `ErrGasLimitTooHigh`

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 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 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 change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
* eth/gasestimator: early exit for plain transfer and error allowance
* core, eth/gasestimator: hard guess at a possible required gas
* internal/ethapi: update estimation tests with the error ratio
* eth/gasestimator: I hate you linter
* graphql: fix gas estimation test
