Gaurav Shukla a83004c806 [TORCH][MLIR] Fold trivial cases of `aten.to.dtype` and `aten.view` op
- It folds `aten.to.dtype` when the input tensor type and result type
  are exactly same.
- It folds `aten.view` when the rank of both the input tensor type and
  result type is unity.

Yi Zhang d8ba68119e Lower aten::view with linalg.collapse and linalg.expand
We only handle the expanding OR collapsing cases, we do not handle
expanding And collapsing happening at the same time or cases where
it's neither collapsing nor expanding like view of [2,3] for
3x2 tensor.

It's assumed that if a shape list element is got from
`aten.size(tensor, dim)` the corresponding dim is not splitted or
collapsed. This assumption makes it easier to deal with dynamic shapes.

Gaurav Shukla 69eaf9a154 [MLIR][TORCH] Add E2E support for `torch.aten.view`
- This commit adds lowering of `aten.View` to `linalg.TensorExpandShape`.
- This lowering will be successful only when one or more static
  dimensions are expanded.
- It also fixes a typo in `ConvertAtenFlattenUsingIntsOp` conversion
  pattern.
