  [mlir][transform] Improve error message of tracking listener. (#66987)

This PR extends the error message of the tracking listener when
replacement ops cannot be found. That may happen if the applied patterns
replace an op by an op of a different kind or by block arguments.
However, this only matters if there are alive handles to the replaced
op. The new error message mentions that explicitly and reports the alive
handles.
