[5/n] Fix top rounded corners in freeform
If activity bounds match parent app bounds height, don't apply rounded
corners. Freeform activities will not have visible letterboxing except
if eligible for camera compat treatment. Pillarboxing for camera compat
will not have rounded corners to ensure consistency between apps.
Round up aspect ratio calculations in desktop mode to match activity
aspect ratio calculations in core.
