sdm: Add support for LINEAR_FORMAT metadata operation

1. Define LINEAR_FORMAT operation in MetaData.
2. VENUS ouput buffer is linear for NV12_UBWC Interlaced video playback.
   So Video module performs LINEAR_FORMAT operation to set "linearFormat"
   metadata member to NV12 linear format in case of Interlaced video.
3. Handle LINEAR_FORMAT metadata operation in HWC wrapper and gralloc.
