hwc: Add support for YCrCb_420_SP_VENUS(NV21_VENUS)

Browse Source 
* Earlier, camera preview buffers were of NV21(YCrCb_420_SP)
  and the video buffers were of NV12_VENUS(YCbCr_420_SP_VENUS)
  format. Now that the video encoder has support for NV21,
  both the camera and video buffers can be of
  NV21_VENUS(YCrCb_420_SP_VENUS) format.

* If the preview and video buffer sizes are the same,
  CPP double pass to generate video and preview buffers can be
  avoided and the buffers can now be generated within a single pass
  with CPP duplication thereby saving power.

* Add support in gralloc for NV12_VENUS format to achieve
  the same.
