Julien Isorce f4115bcc8c glamor: add support for NV12 in Xv 
Useful when video decoders only output NV12. Currently
glamor Xv only supports I420 and YV12.

Note that Intel's sna supports I420, YV12, YUY2, UYVY, NV12.

Test: xvinfo | grep NV12
Test: gst-launch-1.0 videotestsrc ! video/x-raw, format=NV12 ! xvimagesink

v2: Combine the two texture2Ds on u_sampler.
