Apply overlay changes with config change

In R, when overlay changes a configuration change event is triggered
within the app process affected by the overlay change immediately
after updating the overlay paths of resources objects. All activities
would be relaunched after the configuration changed occurred resulting
in activity life-cycle events occurring for activities running in the
background. Apps may assume that onResume is invoked while they are in
the foreground so we made a fix that triggered the activities to be
relaunched when they are brought to the foreground.

The fix involved storing the asset sequence in the AMS and triggering
a configuration change from the AMS for each process affected by the
overlay change. This created problems where the app may receive a
configuration from the AMS with an updated asset sequence before the
event to handle the application info changing actually updated
resources objects. This resulted in reinflating views with the updated
configuration before the overlays were updated in the underlying
resources objects.

This change allows allows RM to apply changes to application infos when
it sees the asset sequence increase during a configuration change,
rather than having to wait for handleApplicationInfoChanged to run.

Test: launch an app, navigate away from the app, change wallpapers, and
      observe app is relaunched and has correct colors when resumed
