Subject: [PATCH] chore: filter warnings from elaborator in Aztec Macros
 (#5556)

# Description

## Problem\*

Do not report the warnings as error during Aztec Macro compilation

## Summary\*
When Aztec Macro is calling the elaborator, warnings are not
discriminated from errors, so they break contract compilation.


## Additional Context



## Documentation\*

Check one:
- [X] No documentation needed.
- [ ] Documentation included in this PR.
- [ ] **[For Experimental Features]** Documentation to be submitted in a
separate PR.

# PR Checklist\*

- [X] I have tested the changes locally.
- [X] I have formatted the changes with [Prettier](https://prettier.io/)
and/or `cargo fmt` on default settings.
