backend/drm: introduce page-flip tracking struct
Introduce a per-page-flip tracking struct passed to the kernel
when we request a page-flip event for an atomic commit. The kernel
will pass us back this pointer when delivering the event.
This eliminates any risk of mixing up events together. In particular,
if two events are pending, or if the CRTC of a connector is swapped,
we no longer blow up in the page-flip event handler.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3753
