[IvanYashchuk]

Relanding #46862
There was an issue with the simultaneous merge of two slightly conflicting PRs.

This PR adds torch.lu_solve for complex inputs both on CPU and GPU.

@zou3519 I didn't notice that you imported the pull request and applied some changes after that. It may need to be re-imported.
Recently tests for linear algebra routines were moved from test_torch.py to test_linalg.py that's why the git diff is smaller and looks a bit different. Effectively it's all the same code as it was.
