gl-renderer: add support of WL_SHM_FORMAT_YUV420

This patch allow gl-renderer to accept WL_SHM_FORMAT_YUV420 buffers.

In a gstreamer pipeline, the support of the WL_SHM_FORMAT_YUV420 by
weston avoid pixel conversion between software decoders and waylandsink.
Indeed, software decoders output I420 (YUV420 planar) that will
match with WL_SHM_FORMAT_YUV420.
