feat: Optimism L2 Block Validation

[hashcashier]

This PR adds support for validating OP L2 Blocks by passing in the --network=optimism parameter.

The main changes for this feature are:

• A dedicated op-block guest binary for optimism L2 block validation.
• A generic ConfiguredBlockBuilder parameterized by a NetworkStrategyBundle that wraps around the BlockBuilder.
  • EthereumBlockBuilder is an alias for ConfiguredBlockBuilder<EthereumStrategyBundle>.
  • OptimismBlockBuilder is an alias for ConfiguredBlockBuilder<OptimismStrategyBundle>.
• Abstraction of TxEssence and implementation of EthereumTxEssence and OptimismTxEssence.
• Profiling of guest runs through the --profile argument at runtime rather than a feature flag on compilation.
• Introduction of the optimal --network parameter with ethereum and optimism as valid arguments.
• Delegation of the state update logic to the implementation of the DatabaseCommit trait from revm.
• Introduction of the OptimismTxExecStrategy.

The readme is updated to include a quick optimism test example:

$ RUST_LOG=info ./target/release/zeth \
    --network=optimism \
    --rpc-url="https://opt-mainnet.g.alchemy.com/v2/YOUR_API_KEY" \
    --cache \
    --block-no=107728767

Tested (and works) on Bonsai.
