video-converter: Add fast paths from v210 to I420/YV12, Y42B, UYVY and YUY2
These then don't require going through the generic code path via AYUV64 first but can be converted directly. This speeds up processing of videotestsrc ! v210 ! videoconvert ! other_format ! fakesink by a factor of 1.55 for I420/YV12 and 1.40 for the other destination formats and reduces memory pressure considerably.
