MLIA-546 Merge AIET into MLIA

Merge the deprecated AIET interface for backend execution into MLIA:

- Execute backends directly (without subprocess and the aiet CLI)
- Fix issues with the unit tests
- Remove src/aiet and tests/aiet
- Re-factor code to replace 'aiet' with 'backend'
- Adapt and improve unit tests after re-factoring
- Remove dependencies that are not needed anymore (click and cloup)
