Add TASK_LAUNCHING_BEHIND to change flags

Browse Source 
When ActivityRecord#mLaunchTaskBehind is true, the newly-launched
task is positioned behind home. However, for compatibility reasons,
it's marked as visible, so there's no way for Shell to tell if a
newly launched task should be shown to the user or not.

This CL adds a transition change flag for this purpose.
