Subject: [PATCH] tests: enable execution of amsterdam statetests (#34671)

:wave:

This PR makes it possible to run "Amsterdam" in statetests. I'm aware
that they'll be failing and not in consensus with other clients, yet,
but it's nice to be able to run tests and see what works and what
doesn't

Before the change:
```
$ go run ./cmd/evm statetest ./amsterdam.json
[
  {
    "name": "00000019-mixed-1",
    "pass": false,
    "fork": "Amsterdam",
    "error": "unexpected error: unsupported fork \"Amsterdam\""
  }
]
```
After
```
$ go run ./cmd/evm statetest ./amsterdam.json
{"stateRoot": "0x25b78260b76493a783c77c513125c8b0c5d24e058b4e87130bbe06f1d8b9419e"}
[
  {
    "name": "00000019-mixed-1",
    "pass": false,
    "stateRoot": "0x25b78260b76493a783c77c513125c8b0c5d24e058b4e87130bbe06f1d8b9419e",
    "fork": "Amsterdam",
    "error": "post state root mismatch: got 25b78260b76493a783c77c513125c8b0c5d24e058b4e87130bbe06f1d8b9419e, want 0000000000000000000000000000000000000000000000000000000000000000"
  }
]
```
