    wayland/pointer: Use grab helper that doesn't focus when disabling
    
    Instead of using meta_wayland_pointer_end_grab() which focuses the new
    grab, add a new helper mean to be used to reset the grab state without
    changing the pointer focus. When using this function, the call site is
    supposed to explicitly manage focus.
