Removed torch.qr and added torch.linalg.qr

[IvanYashchuk]

torch.qr was deprecated in the 1.9 release and will be removed in the next 1.11 release. This PR removes qr and replaces it with the linalg_qr.

pytorch/pytorch#70989 that removes deprecated functions in PyTorch is currently blocked by pytorch/xla.

@IvanYashchuk head is green again, please rebase and the build should pass

[JackCaoG]

mostly lgtm

@IvanYashchuk Is the upstream pr going to make it to the pytorch 1.11? We will do our branch cur soon too.

[IvanYashchuk]

It won't merged for 1.11 branch cut. Because of some internal issues removing of these deprecated functionality is postponed to the next 1.12 release.

[JackCaoG]

@IvanYashchuk Sounds good. We have a large pr we need to merge to pt/xla 1.10 and I was waiting for you to merge your pr first. I guess in this case I will try to merge that giant pr and it might cause some merge conflicts for you.
