[mlir] added a check in the walk to prevent catching a cos in a nested region (#190064) The walk in SincosFusion may detect a cos within a nested region of the sin block. This triggers an assertion in `isBeforeInBlock` later on. Added a check within the walk so it filters operations in nested regions, which are not in the same block and should not be fused anyway. --------- Co-authored-by: Yebin Chon <ychon@nvidia.com>
