Add torch.compile support for all ops

[NicolasHug]

We should add support for torch.compile in all of our ops (meta implem, symint support, etc.) and use the opcheck test suite. See https://docs.google.com/document/d/1W--T6wz8IY8fOI0Vm8BF44PdBgs283QvpelJZWieQWQ/edit#heading=h.pnrqcv6bkfn3 for more details.

• nms: Meta implementation for nms #7944 Add opcheck testing for nms #7961
• RoiAlign https://github.com/pytorch/vision/pull Add opchecks for RoiAlign #8057
• PSRoiAlign PSRoiAlign: SymInt support + meta-implem #8058
• RoiPool RoIPool: SymInt support + meta-implem #8061
• PSRoiPool PSRoiPool: SymInt support + meta-implem #8062
• DeformConv2D DeformConv2d: SymInt support + meta-implem + opchecks #8063

Current status: all the ops above now have proper support for torch.compile except for some MPS-related issues, which we can leave out for now. I had to remove opcheck testing for the ops below because the opcheck suite isn't really compatible with pytest parametrized tests ATM. We should still add manual tests for them though:

• PSRoiAlign
• RoiPool
• PSRoiPool

EDIT: all done in #8144
