Purpose or design rationale of this PR

1. Add GetMemoryExpansionCost.
2. Consider the memory expansion costs in GetKeccak256Gas.
3. Consider proxy => delegate costs for each message:

total += GetMemoryExpansionCost(36) * numL1Messages // staticcall to proxy
total += 100 * numL1Messages // read admin in proxy
total += 100 * numL1Messages // read impl in proxy
total += 100 * numL1Messages // access impl
total += GetMemoryExpansionCost(36) * numL1Messages // delegatecall to impl

4. Add GetMemoryExpansionCost(totalL1CommitCalldataSize).
