  [MLIR][Vector] Add Lowering for vector.step (#113655)

Currently, the lowering for vector.step lives
under a folder. This is not ideal if we want
to do transformation on it and defer the
 materizaliztion of the constants much later.

This commits adds a rewrite pattern that
could be used by using
`transform.structured.vectorize_children_and_apply_patterns`
transform dialect operation.

Moreover, the rewriter of vector.step is also
now used in -convert-vector-to-llvm pass where
it handles scalable and non-scalable types as
LLVM expects it.

As a consequence of removing the vector.step
lowering as its folder, linalg vectorization
will keep vector.step intact.
