no tests for SDPA?

[ArmRyan]

There were no tests added because it was not a new function essentially, just a new call with the idea is that it is tested elsewhere. We have tested it functionally just not with a unit test

[digantdesai]

adding test_sdpa.py would ensure we can lower and run it. Where else it is tested? Couldn't find it in the test/ops dir.

[ArmRyan]

It is tested from the QNN delegate but I can add unit tests here also! I will push that when I can ( probably Monday )

[ArmRyan]

Sorry for the delay, had some issues and went on holidays, came back to more issues so I have removed SDPA for now

[digantdesai]

Silu part LGTM. Add SDPA tests?

Huggingface fails seems unrelated
