Add TracerConfig Support and Implement Contract Tracer

[JukLee0ira]

Proposed changes

1. Add TracerConfig to Existing Tracer:

   • Added a TracerConfig option, primarily for onlyTopCall, to provide more control over which calls are traced.

2. Implement ContractTracer:

   • Introduced a new ContractTracer to locate created contracts and return their addresses.
   • Added configuration options to retrieve the corresponding contract bytecode when needed.

[s1na]

I would return an error here instead. No reason to do tracing in this case.

[s1na]

This is not quite right. The inout here will not be the actual bytecode. Rather the contract constructor code.

Also here the input is constructor code
