RFC: turnip, wsi: Allow building without drm/msm

What does this MR do and why?

Various changes to allow compiling Turnip with only kgsl and X11 enabled.

With these patches it's possible to build Turnip without drm/msm via meson setup build -D platforms=x11 -D dri3=enabled -D gallium-drivers= -D vulkan-drivers=freedreno -D freedreno-kmds=kgsl -D buildtype=release and then use it with MESA_VK_WSI_DEBUG=sw.

The commits here fix the following compilation errors:

Draft/WIP because I'm not sure what to return in tu_wsi_can_present_on_device and if the check in wsi_x11_check_dri3_compatible is appropriate.
