9cae3d5e94 tests: Add fuzzer initialization (hold ECCVerifyHandle) (practicalswift)
Pull request description:
The fuzzers `eval_script` and `script_flags` require holding `ECCVerifyHandle`.
This is a follow-up to #17235 which accidentally broke those two fuzzers.
Sorry about the temporary breakage my fuzzing friends: it took a while to fuzz before reaching these code paths. That's why this wasn't immediately caught. Sorry.

a27a2957ed [validation] Add CValidationState subclasses (John Newbery)
Pull request description:
Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
```
