surface: add new chroma formats.

Browse source 
Add new chroma formats available with VA-API >= 0.34.0. In particular,
this includes "RGB" chroma formats, and more YUV subsampled formats.
Also add a new from_GstVaapiChromaType() helper function to convert
libgstvaapi chroma type to VA chroma format.
