seat/pointer: add wl_pointer.warp event support

Browse source 
Add support for the wl_pointer.warp event from Wayland protocol version 11.
https://gitlab.freedesktop.org/wayland/wayland/-/merge_requests/340

This allows the compositor to notify clients when the pointer position has
changed due to surface movement or compositor action, rather than input device
motion. This is useful for tracking cursor position across surface boundaries
and dynamic repositioning.
