Force client composition if we'd use rotator

HWC can only handle a certain range of scaling values, and will
fall back into rotator mode otherwise. However, there is an issue
at the moment with the rotator that leads to one missed frame
when enabling it, and we're better off with GL comp in that
case.

Add some temporary hack to force GPU composition if we detect
that the scaling value is set to a value that would put us into
rotator mode.

Test: Have some animation with a lot of scaling, observe no
jank.
