noncliff: fix #418: inconsistency in multi-qubit projections for MixedDestabilizer/Stabilizer states

[Fe-r-oz]

This PR fixes the inconsistencies that we see when testing projection using multi-qubit random_stabilizer states and multi-qubit random_pauli operator for Stabilizer and MixedDestabilizer. Multi-qubit tests have been been added to demonstrate the consistency of projection test now.

Detail about investigation are included in #418.

Edit: The primary issue in the current testing lies in a scaling discrepancy within one branch, as demonstrated in the tests in #418.

This PR is ready for review, Thank you!

Edit:
Improved the code quality by doing normalization and using random_clifford. This test will serve as a baseline test.

Thanks for the fix. If I understand correctly, this is an issue with a feature that is not yet implemented. These tests should just be added whenever that feature is submitted as a PR (in that same PR)
