We disable modifiers for two reasons: an udev rule saying so, or the lack of a working drmModeAddFB2(). However, to the users, this is not granular enough. While the current user, whether to enable modifiers in MetaRendererNative, doesn't need more granularity, we want to send modifiers to Wayland clients even if the onscreen framebuffers should still be allocated without modifiers. Prepare for differentiating between how Wayland DMA buffers work and how onscreen buffer allocation work by separating the relevant device flags.
