DesktopTasksController: Supply displayId when re-launching bg apps.

When launching background apps we don't go through the normal flow -
launcher requests a re-launch of background apps since they are depicted
as "minimized". Because this is a different codepath, we end up creating
a different ActivityOptions, and by default without a displayId supplied
the task ends up being launched into default display.

This also passes displayId into startLaunchTransition so the desk
activation work can be properly setup.
