This MR adds support for handling `wl_pointer` devices:
1. Handle enter/leave/(absolute) motion/button/axis events to allow users to interact with applications using such devices, e.g., a mouse. 2. Update the cursor image used for Wayland surfaces based on the Windows cursor bitmap data.
A few notes:
1. A single `wl_seat`/`wl_pointer` is supported for now. 2. Many of the input interactions require window management support that hasn't been implemented yet (e.g., popup positioning, resizing, max/fullscreen). 3. There is some potential for bad interactions between the input event dispatching mechanism and the `win32u` flushing logic for `window_surface` , which can lead to visual glitches. Although I don't think this is blocker for this MR, I would like to start a discussion about the problem and mitigation ideas in a [comment](https://gitlab.winehq.org/wine/wine/-/merge_requests/3686#note_43830) below.
Thanks!

Track the availability of a pointer device for a seat.

Thanks, I have updated the MR to use the simpler approach, as discussed above.
Fwiw you could perhaps also do wl_surface_set_user_data(wl_surface, 0) when it is destroyed, but I don't know how whether it synchronizes properly or if it would then require locking.
Access to Wayland object user data is not internally synchronized, and would require locking similar to what we do with the `xdg_surface` user data. In addition, I don't find the benefit to be substantial enough: even if we clear the HWND on `wl_surface` destruction, we are only decreasing, not eliminating, the possibility of an event handler using an invalid HWND value (e.g., the window may be destroyed right after we read the HWND in `pointer_handle_enter`)
Rémi Bernon (@rbernon) commented about dlls/winewayland.drv/wayland_pointer.c:
uint32_t serial, struct wl_surface *wl_surface, wl_fixed_t sx, wl_fixed_t sy){
- struct wayland_pointer *pointer = &process_wayland.pointer;
- HWND hwnd;
- if (!wl_surface) return;
Is it really allowed to have NULL surface?
Looks okay I think. (I'm assuming the wl_surface checks are there for a reason)

Yes, if the `wl_surface` (and more generally any wayland object that is used as an argument to an event) is destroyed by the client before the client queues the respective event that references it, we will get [a NULL value](https://gitlab.freedesktop.org/wayland/wayland/-/blob/edb943dc6464697ba13d7d...) for it. It is during the queuing process that libwayland [acquires an additional reference](https://gitlab.freedesktop.org/wayland/wayland/-/blob/edb943dc6464697ba13d7d...) to any object arguments to keep them alive until dispatch.

Indeed it does, but this is an actual value I have seen on my system (with the `light` theme). It's not always that bad, although a quick test shows that the mean duration of `UXTHEME_ScrollBarDraw` is ~13ms with Wayland and ~10ms with X11, which is still a lot. FWIW, the majority of the time is spent drawing the top and bottom arrows of the scrollbar. There is certainly room for optimization here, but the timing of this particular scenario is just an example. Any frequency of motion events/messages that's higher than the message loop frequency will cause the loop to not become idle, and will lead to artifacts if sustained long enough (e.g., consider motion events every 2ms with a 3ms draw/loop period). I suspect we will have a similar problem with sustained resize events.
For this I think maybe GetMessage should be in charge of making sure surfaces are flushed often enough. Maybe just a matter of calling `flush_window_surfaces( FALSE )` unconditionally in `check_for_driver_events`, as it's throttled internally already.
