AAPT2: Fix compatible-screens element in AndroidManifest.xml

Fix an issue where the compatible-screens element was not being
populated correctly. The previous version was missing the screenSize
attribute which is mandatory. The attributes were also missing the
resource ID from the framework library as these are a part of the public
API.
