vp9: postencode drop frame for screen content in CBR. Encode the next frame at max q. For layers: post_encode_drop is only check on base spatial layer, and if base is post-encoded-dropped, then whole superframe is dropped. Added API to guard postencode dropping. Turned off by default. Added unittest. BUG=b/112990050 Change-Id: I42fee279014aca616f7a4d9b582cb2bf5da2f2e7
