Bin Bao e8f4c9cc40 [LT] Upstream LazyView and view ops IR Nodes (#69277) 
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/69277

LazyView is the main class for tracking alias caused by view
ops. The corresponding IR classes for view ops are hand-written now, and
we can switch to code-gen them in future. For certain view ops, they
have a reverse IR class to perform inplace update in the backward
direction on a chain of alias ops.

As part of the future work, we will simplify the logic for LazyView once
the functionalization pass in core is ready to use.
