Feat: custom Evm trait

[julio4]

📝 Summary

• Definition of a new Evm trait with only one method transact.
• Evm from reth_evm, aliased as RethEvm, auto-implement this new Evm when trait bounds are satisfied.
• EvmFactory's create_evm methods return Evm trait objects.
• Update codebase to reflect these changes, such as mutating the db before creating evm in payout_tx

💡 Motivation and Context

This PR introduces a new trait Evm based on reth_evm::Evm but with more concrete trait bounds and less methods (only transact). It also simplifies the EvmFactory trait by removing the associated Evm type and not being constrained by revm inspector trait bounds.

All the logic of EthCachedEvmFactory stays the same, and this PR is mostly for better abstraction and giving more control to exactly what the Evm should provide to rbuilder.

✅ I have completed the following steps:

• Run make lint
• Run make test
• Added tests (if applicable)
