chore: add serde-bincode-compat for re-export features (#397)

## Motivation

Until reth completely moves off of `op-alloy-consensus`, and onto
`maili-consensus`, we'll want to enable this transitive dependency
feature from the `op-alloy-consensus` dep.

## Solution

Add `serde-bincode-compat` feature to `op-alloy-consensus` and propagate
to `maili-consensus`
