mesa/formats: Add support for 10 and 12 bit SW decoder YCbCr formats

Matching e.g. I420_10LE in Gstreamer / yuv420p10 in ffmpeg. The formats
are notably used for HDR10 videos by software decoders like dav1d, libav,
libaom and libvpx.

Use-cases include video players and editors that can allocate DMA buffers
- e.g. via udmabuf, dma-heaps, VA-API, V4L2, etc. - allowing them to avoid
unnecessary copies. Testing HDR10 playback on CI might also become easier.
