wayland: Implement 'DISABLED' cursor mode

Browse Source 
This implements support for the 'DISABLED' cursor mode, which
effectively means locking the pointer to the surface. The cursor is also
explicitly hidden.

This adds two new build dependencies: wayland-scanner and
wayland-protocols.

Closes #708.
