wayland: Support the cursor-shape protocol

Browse Source 
If present, use the cursor-shape protocol instead of manually
updating a pointer surface. This commit supports both v1 of the
protocol and the (still unmerged) v2 additions to the enumeration.

This was tested with both kwin and mutter.

(cherry picked from commit a63d6d1dc7a8ebdf61c682196f89917846cbe8ac)

Note that there are some groups of cursor shapes that are related:
The first group is drag-and-drop cursors which are used to indicate
the selected action during dnd operations. The second group is resize
cursors which are used to indicate resizing and moving possibilities
on window borders. It is recommended that the shapes in these groups
should use visually compatible images and metaphors.

Sets the device cursor to the specified shape. The compositor will
change the cursor image based on the specified shape.
The cursor actually changes only if the input device focus is one of
the requesting client's surfaces. If any, the previous cursor image
(surface or shape) is replaced.
The "shape" argument must be a valid enum entry, otherwise the
invalid_shape protocol error is raised.
This is similar to the wl_pointer.set_cursor and
zwp_tablet_tool_v2.set_cursor requests, but this request accepts a
shape instead of contents in the form of a surface. Clients can mix
set_cursor and set_shape requests.
The serial parameter must match the latest wl_pointer.enter or
zwp_tablet_tool_v2.proximity_in serial number sent to the client.
Otherwise the request will be ignored.
