Per-app config for split screen aspect ratio
We're defining a new compat framework change id that indicates whether a
given app should use the split screen aspect ratio.
Test: As manual testing use 'adb shell am compat disable/enable 208648326 <package-name>'. For the unit tests run 'atest WmTests:SizeCompatTests'.
Fixes: 208648326
Change-Id: I0232d6d98b10e546b840c08ffbf6e7be9c465965
