Disallow pinned stack to control occluded state.
In the original design, we check the top focus stack of each display
to control its occlusion state. However, the start time of pinned activity
may start later than the user's application, such as PipMenuActivity. In
which case the top focus activity will not be what the user expects.
To prevent this, we can ignore Pinned stack when checking visibility for
a display.
