Do not always report configuration change to activity

Activity that does not handle any of the configuration changes was not
relaunched when only changing its size and without cross the size
threshold, see ActivityRecord#crossesSizeThreshold(), but the
new configuration would still be scheduled to the client.

In that case, Activity#onConfigurationChanged() was called when
ActivityConfigurationChangeItem executed, because it requested to
always report to the activity. This was wrong since the activity didn't
request to handle any of the configuration changes.

On the other hand, if configuration change sent from view root came
earlier than ActivityConfigurationChangeItem, the new configuration
change did not propagate to ResourcesManager.

Allow the new configuration changes propagate to ResourcesManager
and report to activity only if the activity has been declared to handle.
