Cap resolution for pre-S apps on TV at 1080p

On Android TV applications that target pre-S SDK are not expecting to
receive a Window larger than 1080p.
To avoid this from happening this CL overrides compatibility scaling for
applications that target a pre-S SDK on ATV devices that have larger than
1080p screen, so that the applications would still need to draw to a
1080p Surface.
