render/pixman: Add dmabuf support

Browse source 
Adds linux-dmabuf support to the pixman renderer.  The main reason is so
clients can use GPU-accelerated rendering even if the compositor is
using the pixman renderer for whatever reason.  This also allows the
pixman renderer to import dmabufs (only RGB/ARGB formats, not YUV for
now).

Since after this change all renderers store a DRM FD, I move the drm_fd
from the individual implementations to the shared wlr_renderer base.
This means that renderer_autocreate() can set pixman's drm_fd for it and
the pixman renderer doesn't have to know about DRM at all.
