draft: replace revm execution paths with evm2

[onbjerg]

Draft only. This is just an experiment/PoC hacky integration of evm2. This is not mergeable.

Replaces the main revm-backed execution paths with evm2 and removes the revm dependency from the workspace. This gets sync execution running through evm2, but the branch is intentionally dirty and still has several parked/stubbed paths.

Known remaining work:

• Untangle SpecId handling.
• Unvendor the temporary reth-core crates.
• Misc cleanup across touched crates.
• Untangle abstractions that are revm-specific rather than evm2-specific.
• Re-add inspectors and re-enable stubbed features:
  • reth-bb / BAL execution paths.
  • RPC call, estimate gas, trace, debug, simulate, and bundle execution helpers.
  • Custom inspector and precompile-cache examples.
  • Payload builder / BAL hooks that were parked.
  • Invalid-block/reorg witness paths that previously relied on revm inspectors or revm state adapters.
