Add an option to skip unknown transaction types when using `debug_traceTransaction`

[fvictorio]

See https://github.com/NomicFoundation/edr/issues/570 for context, especially this comment.

Tentatively: let's do this with an environment variable. Name TBD, but something like EDR_UNSAFE_SKIP_UNSUPPORTED_TRANSACTION_TYPES could work. This is a mouthful, but the verbosity matches how sure you have to be that you want to use it.

This should only work with the generic chain type, so this is effectively blocked until we have the multichain refactor in place.

Also: we are not going to document this, nor recommend using it when we throw the error described in https://github.com/NomicFoundation/edr/issues/597
