[mlir][Linalg] Avoid collapsing dimensions of linalg op that arent foldable.

The collapsing dimensions transformation is limited to only those
cases where the sequence of dimensions are contiguous in all the
ranges of the indexing maps of the operation. Add this check before
applying the transformation.
