feat(rpc): Add EvmEnvConverter for custom effects on the EvmEnv

[RomanHodulak]

Closes #17935

Adds a new converter to RpcConvert that can apply custom effects on the EvmEnv.

The conversion is EvmEnv -> EvmEnv meaning there is no different type at the output.

This is simply an override so I think EvmEnvOverrides/RpcEnvOverrides would be a better name here?

Also it seems that #17935 suggests extracting entire prepare_call_env logic into the overridable handler so would like a review from @mattsse here

[mattsse]

after looking at #17792 again this is basically a subset of this and we solved #17935 differently
