Notify all packages is uid-mode is changed

Multiple packages might share a UID, but appOpsService might not have
cached the uid->package mapping for those yet. Hence the only way to
list all packages for a uid is to ask package manager.

setUidMode already handled this correctly, hence factor out the code
into notifyOpChangedForAllPkgsInUid and reuse it from
commitUidStatePendingLocked.
