Description

Problem*

Same PR as #8084
I re-do it due to issues with PR review.

Summary*

Add a framework for acir-gen unit tests.
It generates SSA for a single instruction, converts it using acir-gen and execute it.
Then we compare the result with a SSA evaluation using constant folding.
All 'simple' instructions are covered, in particular all the binary instructions.
More tests with different types or missing instructions such as array operations and calls could be added in future.

Additional Context

Documentation*

Check one:

  • No documentation needed.
  • Documentation included in this PR.
  • [For Experimental Features] Documentation to be submitted in a separate PR.

PR Checklist*

  • I have tested the changes locally.
  • I have formatted the changes with Prettier and/or cargo fmt on default settings.
