Wayland has 3 types of scrolling events:
- axis. Used for e.g., touchpad 2 finger smooth scrolling
- axis_discrete. Used for mouse scroll wheels (i.e., notches)
- axis_value120. Used for high resolution input devices
Wine currently only supports axis_discrete, meaning that
2 finger scroll events get ignored.
This commit tries to add basic support for axis scrolling events,
by translating the smooth motion in scroll increments using some
primitive assumptions about line height and number of lines to scroll.

v11: wip! winewayland.drv: Try to support smooth scroll events
https://gitlab.winehq.org/wine/wine/-/merge_requests/4809
Instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/7815, for https://gitlab.winehq.org/wine/wine/-/merge_requests/7226, this only split the sync ops to a separate vtable and let objects delegate theirs to a separate object.
This starts using a event-like interface for most objects, leaving the decision regarding if/how to split sync themselves / integrate inproc syncs for later.

v8: server: Use an event sync for fd objects.
server: Introduce a new event sync object.
server: Redirect fd-based objects sync to the fd.
server: Add an operation to retrieve an object sync.
server: Move object grab/release out of (add|remove)_queue.
