Do not relaunch bg activities when application info changes

Update the configurations via ActivityTaskManager to prevent the
activities being relaunched while in background. Instead, the
activities will be relaunched after brought to front and being visible.

This also prevents all activities in the system being relaunched
at the same time.

For framework resource updates, the global configuration will be
updated.

For individual package overlay changes, new asset sequence would be
set to the activity's requested configurations to ensure the activity
will be relaunch once visible. The requested asset sequence will be
reset if its parent has a newer asset sequence.
