media: Add BGR48_12 video format

BGR48_12 is a reversed RGB format with 12 bits per component like BGR24,
expanded to 16bits.
Data in the 12 high bits, zeros in the 4 low bits,
arranged in little endian order.

12 Bits Per Component
==============================
These formats store an RGB triplet in six or eight bytes, with 12 bits per component.
Expand the bits per component to 16 bits, data in the high bits, zeros in the low bits,
arranged in little endian order.
