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.

In many cases, there is a need to create somewhat nontrivial bytecode. A
recent example is the verkle statetests, where we want a `CREATE2`- op
to create a contract, which can then be invoked, and when invoked does a
selfdestruct-to-self.
It is overkill to go full solidity, but it is also a bit tricky do
assemble this by concatenating bytes. This PR takes an approach that
has been used in in goevmlab for several years.
Using this utility, the case can be expressed as:
```golang
// Some runtime code
runtime := program.New().Ops(vm.ADDRESS, vm.SELFDESTRUCT).Bytecode()
// A constructor returning the runtime code
initcode := program.New().ReturnData(runtime).Bytecode()
// A factory invoking the constructor
outer := program.New().Create2AndCall(initcode, nil).Bytecode()
```
We have a lot of places in the codebase where we concatenate bytes, cast
from `vm.OpCode` . By taking tihs approach instead, thos places can be made a
bit more maintainable/robust.
This adds an API method `DropTransactions` to legacy pool, blob pool and
txpool interface. This method removes all txs currently tracked in the
pools.
It modifies the simulated beacon to use the new method in `Rollback`
which removes previous hacky implementation that also erroneously reset
the gas tip to 1 gwei.

The [kilic](https://github.com/kilic/bls12-381) bls12381 implementation
has been archived. It shouldn't be necessary to include it as a fuzzing
target any longer.
This also adds fuzzers for G1/G2 mul that use inputs that are guaranteed
to be valid. Previously, we just did random input fuzzing for these
precompiles.
This is one further step towards removing account management from
`geth`. This PR deprecates the flag `unlock`, and makes the flag moot:
unlock via geth is no longer possible.
This change invokes the OnCodeChange hook when selfdestruct operation is performed, and a contract is removed. This is an event which can be consumed by tracers.
This PR moves chain config related code (config file processing, fork
logic, network defaults) from `beacon/types` and `beacon/blsync` into
`beacon/params` while the command line flag logic of the chain config is
moved into `cmd/utils`, thereby removing the cli dependencies from
package `beacon` and its sub-packages.
When `evm statetest --bench` is specified, benchmark the execution
similarly to `evm run`.
Also adds the ability to filter tests by name, index and fork.

Here I'm adding a new helper function that extracts the revert reason of
a contract call. Unfortunately, this aspect of the API is underspecified.
See these spec issues for more detail:
- https://github.com/ethereum/execution-apis/issues/232
- https://github.com/ethereum/execution-apis/issues/463
- https://github.com/ethereum/execution-apis/issues/523
The function added here only works with Geth-like servers that return
error code `3`. We will not be able to support all possible servers.
However, if there is a specific server implementation that makes it
possible to extract the same info, we could add it in the same function
as well.
