protocol: add wl_pointer.warp event

Browse source 
The original wl_pointer.button event does not contain the position information.
In some scenarios, the client cannot obtain the correct position information.
For example, when the mouse focus is on a button and the mouse does not move
but the window size changes, the client cannot update the position information
through the motion event, resulting in incorrect mouse position.

Therefore, This event should be sent when the local coordinates of a pointer
change as a result of surface being moved/resized/fullscreened.

<description summary="pointer warp event">
Notification of pointer location change within a surface.
This location change is not due to events on the input device,
but because either the surface under the pointer was moved and
thus the relative position of the pointer changed, or because
the compositor changed the pointer position in response to
an event like pointer confinement being exited. The arguments
surface_x and surface_y are the location relative to the
focused surface.
This event must not occur in the same wl_pointer.frame as a
wl_pointer.enter or wl_pointer.motion event.
