EmulatedFakeCamera2: Add recording support for 320x240, NV21. DO NOT MERGE

Browse Source 
- Support 320x240 in addition to 640x480
- Support NV21 (monochrome only right now)
- Base simulated time on system time,
  since stagefright cares about timestamp base
- Use emulator magic gralloc format to enable gralloc to pick format based on
  destination.
