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.

Add support for int types in gtScalar op.

Support for integer types in gtScalar op has been added.
The code share same logic with gtTensor op and can be merged
which is added as a TODO.

Add `aten.gt.Tensor` op

`aten.gt.Tensor` op has been added in torch dialect and the
lowering of the op has been done to the linalg dialect.
