feat(cast): add trace and debug on local contracts

[zerosnacks]

Component

Cast

Describe the feature you would like

From #6887

Using cast run and cast call to trace and debug can currently only fetch abi and source from explorers such as etherscan. In situations where no explorer is available, it would be intuitive to use the abi and source provided by the local files.

Proposed solution:

As with forge debug - using local files is preferred over fetching data from remote explorer. Only if etherscan_api_key is defined, will we fetch abi and source from the explorer.
Without explorer it should now compile solidity files and fetch contract bytecode from build output. To identify contract addresses it should fetch on-chain bytecode via RPC call. Most of the required code change likely happens in handle_traces, where the decoder and debugger is fed with the required data fetched from local files (and RPC).

Points of attention:

• Debugging on inherited contracts does not resolve to the respective source code.
• Can we use existing build artifacts instead of running the builder each time? This also solves the problem where the building source requires additional parameters.

Additional context

Previously implemented in #6887, contributor is recommended to use that as a reference or build on top
