wayland: Support complex (YUV) pixel formats

Browse Source 
In the previous commits, we added the possibility to use pixel formats
which are complex (YUV-based and/or multi-planar) inside Cogl. Use this
new feature by assuming we get a CoglMultiPlaneTexture, rather than a
"simple" CoglTexture.

To easily test whether this works, one can use GStreamer pipelines
(you'll need gst-plugins-bad for this to work):

For normal BGRA (this should already work before this commit):

```
$ gst-launch-1.0 videotestsrc ! "video/x-raw" ! waylandsink
```

For NV12 (a popular video format):

```
$ gst-launch-1.0 videotestsrc ! "video/x-raw,format=NV12" ! waylandsink
```

For YUV 4:2:2 (another video format):

```
$ gst-launch-1.0 videotestsrc ! "video/x-raw,format=Y42B" ! waylandsink
```

You can also replace with other video sinks, like `vaapisink`.

`glimagesink` also works, but for some reason seems to unconditionally
convert to RGBA before submitting a texture (so it doesn't do a lot
really).
