Each color component is stored in the 1st byte with bit 0~7, with 2 extra high bits 8~9 will be stored in 2nd byte. For the rest 6 bits of 2nd byte are filled with the next color with bit 0~5.

The Full-G format adopts some of the features of Bayer CFA and RGB. In R and B Channels, only the pixel value of the corresponding position under the CFA arrangement is recorded.

Add packed/full-g bayer formats with 8/10/12/14 bit for image output. Add Pass 1 (P1) specific meta formats for parameter processing and 3A/other statistics. (The current metadata format used in meta input and partial meta nodes is only a temporary solution to kick off the driver development and is not ready to be reviewed yet.)
