glamor: Add support for exporting depth 16 pixmaps.

Browse Source 
With a patch to mesa to expose rgb565 pbuffers even on a server with
only depth 24 and 32 visuals, fixes
dEQP-EGL.functional.render.single_context.gles2.rgb565_pbuffer.  Those
pbuffers (or at least something renderable with 565) are required by
the current CTS for GLES3, and having the server support DRI3 on those
pixmaps means that we can avoid having a different path for EGL
pbuffers compared to pixmaps.
