Iterate over all swipeable regions when calculating quickswitch gesture bounds

Previously when creating a new CurrentDisplay, we would
never get the correct OrientationRectF from the hashmap
because the size field of CurrentDisplay would be incorrect
for a given rotation.
Ex. Rotation 0 and Rotation 1 would have inverted display sizes
Thus hashcode would return different values and we would only
ever see if a point is contained in the current rotation's
OrientationRectF.

Test: Tested swiping from portrait to landscape app, was
able to swipe continuously
