  [mlir][transform] Fix TrackingListener in regions that are isolated from above

When an operation is removed/replaced, the TrackingListener updates the internal transform state mapping between handles and payload IR. All handles must be updated, even the ones that are defined in a region that is beyond the most recent region that is isolated from above.

This fixes a bug, where a payload op was erased in a named sequence. Not only handles defined inside of the named region must be updated, but also all other handles such as the ones where the sequence is included.
