Update screenshot requests to render proper crop and rotation.

The previous screenshot requests in SystemUI would generate a bitmap
and then adjust crop and rotation afterwards. Bitmaps from screenshots
are now hw Bitmaps so they can't be updated in software. Instead request
the proper crop and rotation from the native code to generate a Bitmap
with the correct configurations.
