Allow direct access to the pixel data of linux_dmabuf_v1 buffers by
mmapping the FD. This causes a wait on any outstanding fences and also
triggers the DMA_BUF_SYNC mechanism to do any cache fiddling needed.
This doesn't support multi-planar formats (e.g. YUV420 from hardware
codecs)
I also fix the comment on wlr_renderer.render_buffer_caps (it's used for
textures, not the render target) and update
wlr_renderer_init_wl_display() and
wlr_linux_dmabuf_feedback_v1_init_with_options() to use the renderer's
own claimed buffer_caps instead of hardcoding DMABUF as required.
