meson: Add support for YUV formats

Add support to allocate a number of YUV formats. Particularly around
NV12 which can be used in the camera and encoder. This will allow
allocating/sharing buffers across multiple devices via dmabuf.

BUG=b/159467426
TEST=Allocate NV12 buffer and composite it on the GPU.
