feature: l2 gas estimations

### Component

Other (please describe), Forge

### Describe the feature you would like

in foundry today we have gas estimates, but only the l1 gas used. would love to be able to also see l2 gas/calldata costs to be able to more accurately make decisions between using calldata vs state

Ideal workflow would be something like ‘forge X —function FN_SEL --chain X` and it outputs a usd value, maybe also a breakdown of calldata cost vs gas cost on L2s

### Additional context

Alchemy has a benchmarks repo but done in hardhat, would be nice to be able to use foundry for such flows https://github.com/alchemyplatform/aa-benchmarks/

Start by reviewing Forge's existing gas-estimation workflow and the linked Alchemy aa-benchmarks repository, which uses Hardhat. Define how the proposed `forge X --function FN_SEL --chain X` flow would obtain L2 gas and calldata costs, and consider the requested USD output and cost breakdown as the completion criteria.
