Add P010/P016/P210/P216 semi-planar YUV FourCCs
Microsoft defines these as a plane of Y samples followed by a plane of
interleaved Cb,Cr sample pairs, all 16bit words, the 10bit variants leaving
their 6 least significant bits 0:

DirectShow capture devices advertise P010, so nut needs a name for it
before it can be stored.

Since many exotic planar YUVA pixel formats are not contemplated by
the AVI/QuickTime FourCC lists, the following scheme is adopted for
representing them.
