video: add yuv float formats

Adding all these so I can use them for obscure processing purposes (see
later draw_bmp commit).

There isn't really a reason why they should exist. On the other hand,
they're just labels for formats that can be handled in a generic way,
and this commit adds support for them in the zimg wrapper and vo_gpu
just by making the formats exist. (Well, vo_gpu had to be fixed in the
previous commit.)
