chore(op): L1 receipt rpc methods default trait methods

[emhane]

Ref #8336

• Moves L1 transaction receipt RPC methods into default trait methods on trait EthTransactions
• Introduces new trait EthBlocks, with L1 block receipts RPC logic as default trait methods
• Introduces new trait BuildReceipt, called from both EthBlocks and EthTransactions, with L1 receipt building as default impl
• Abstracts data access behind trait method getters, cache and provider, to allow for reusable control flow logic that works for both OP and L1, which is implemented in default trait methods
• Overrides necessary methods on EthBlocks and BuildReceipt for impl on OptimismApi

love the direction, I think this is exactly what we want.

can merge into scaffolding, or we try it incrementally?

needs to be merged into matt/scaffold-ethapi because atm, it's otherwise broken for op (since code moved out to OptimismApi, but that type isn't plugged in anywhere)
