Start activity with focus root task for staged split

Browse Source 
During the start activity process, the system will get a launch root
task to launch activity. The root tasks are created as a direct child
of a TDA, unless there is a launch-root-task set where the created
task would be a child task of the launch-root-task.

This CL make activity can start with a focus root task which is
created by the task organizer and has an adjacent task. For
legacy split screens, this CL doesn't change the original behavior.
