op-node: split l1 source into eth and l1 client

[protolambda]

In preparation of refactoring the L2 RPC, this splits the L1 RPC source functionality into a more general eth client, and a L1 client that wraps it.

Changes

• Move L1 source into sources package
• Split L1 source into eth client (to be shared with L2 client code) and L1 client (adds the L1 specific client methods)
• Move AccountResult to eth package so it can be shared/used everywhere
• Move ComputeL2OutputRoot to rollup package so it can be used without importing a RPC bindings package
• Change L1Info to more general BlockInfo, and add coinbase header field
• Remove FetchAllTransactions from L1 source bindings (unused for a long time now)
• Cleanup Eth client testing a bit (used to be L1 client test)
• Mirror client bindings structure in mock test utils
• Remove unused BlockToBatch
