cursor-shape: use server-side cursors for custom (OSC-22), if possible

Browse source 
Using a lookup table, try to map the user-provided xcursor string to a
cursor-shape-v1 known shape.

If we succeed, set the user’s custom cursor using server side
cursors (i.e. using cursor-shape-v1).

If not, fallback to trying to load the image ourselves (using
wl_cursor_theme_get_cursor()), and set it using the legacy
wl_pointer_set_cursor().
