[PATCH 0/1] MR9846: winewayland: support wl_seat version 8

[Ashley Hauck (＠khyperia)]

Bump wl_seat from version 5 to version 8 to support the axis_value120 event, required for high resolution scrolling.

- Changes in version 5->6: adding the `shape` and `orientation` events to `wl_touch`. We do not create `wl_touch` objects, so no changes are needed.
- Changes in version 6->7: wl_keyboard.keymap must be mmap'd with MAP_PRIVATE (MAP_SHARED is no longer allowed). We already do so, so no changes are needed.
- Changes in version 7->8: addition of the wl_pointer.axis_value120 event. Implementing it is the purpose of this MR.

This is my first Wine MR. Please let me know if there's anything I can do better!
