Feat/debug tests functions

[anaPerezGhiglia]

Description

Expand debugger funcionality to support debugging test functions and configure an external oracle-resolver url.
This will allow to debug contract tests that hit the TXE

Problem*

Resolves noir-lang#5208

Summary*

• Add the possibility to compile and debug a test function
  • this involved knowing how to compile a specific function that's not the main function
  • it also implied analyzing the execution result (once the debugger finishes) to analyze wether the execution matches the test expectations (some test may be marked to should_fail)
• Add the possibility of configuring an external oracle resolver when debugging
• Move the execution of the debugger to a separate thread from REPL
  • this involved that the repl no longer has a context instance and that instead is spawining a new thread and communicating with the debugger through two channels (one for sending commands and the other for receiving the response)

Additional Context

• instrument contract functions in addition to top-level functions
• extract execution_error_from function into nargo/errors and use it in debugger and nargo/ops/execute
• expose test functions to be able to use it from debugger
• add --test-name and --oracle-resolver arg options to debugger_cmd

Documentation*
