[TorchAO] [OVQuantizer] Update Torch AO Dependency and Refactor Executorch Tests

[anzr299]

Changes

1. Move executorch test reference graphs from tests/torch/fx -> tests/executorch
2. Remove OVQuantizer from NNCF and use this from executorch
3. Remove Quantizer tests from conformance suite.

Reason for changes

(reasons are in the same order as changes above)

1. The tests for executorch were moved from tests/torch/fx -> tests/executorch
2. We need to keep quantizer in one place only
3. For now, need to contain the restrict executorch requirement to only tests/executorch

This is to avoid import of OpenVINO quantizer whose only purpose is type hint

• This xfail is not marked as strict, so if the underlying issue gets fixed the test may silently become XPASS and stop providing signal. Consider setting strict=True (and ideally linking to the tracker/issue URL in the reason) so the suite forces follow-up when the failure condition changes.

Did you check the dot files manually? Is everything working ok?

[daniil-lyakhov]

Why not to call the pre-commit executorch test like
precommit / pytest / executorch?

Yes, I checked the graphs manually

Why not to call the pre-commit executorch test like precommit / pytest / executorch?

@AlexanderDokuchaev asked me to seperate the executorch workflow from others.

LGTM

@AlexanderDokuchaev is it okay? executorch==1.2.0 requires this pytest version.
