ui: Add dpy_gfx_check_format() to check backend shared surface support
This allows VGA to decide whether to use a shared surface based on
whether the UI backend supports the format or not. Backends that
don't provide the new callback fallback to native 32 bpp which
is equivalent to what was supported before.
