Improve testing of inplace views (#59891)
Summary:
Partially addresses https://github.com/pytorch/pytorch/issues/49825 by improving the testing
- Rename some of the old tests that had "inplace_view" in their names, but actually mean "inplace_[update_]on_view" so there is no confusion with the naming
- Adds some tests in test_view_ops that verify basic behavior
- Add tests that creation meta is properly handled for no-grad, multi-output, and custom function cases
- Add test that verifies that in the cross dtype view case, the inplace views won't be accounted in the backward graph on rebase as mentioned in the issue.
- Update inference mode tests to also check in-place
