[MPS] Solve contiguos view tensors using arrayViews instead of blits (#146) (#91743)
Solve contiguous view tensors using arrayViews directly instead of performing blit or gather.
E.g in case of the following example:
```
x = torch.tensor([1,2,3,4], device="mps')
y = x[2:]
r = y + 2
```
Previously, `y` would be materialized using a gather or a blit. With this change, the memory of `y` is aliased directly using arrayViews, thus skipping the need for blit or gather.
Fixes pytorch#85297, pytorch#86048
