Since this signal is in a hot path during input handling, it makes sense not to have this be a signal at all, currently most of the time spent in it is in GLib signal machinery itself. Replace it with a function/user data pair that are set on the sprite itself. Only the places that create an sprite are interested in hooking one ::prepare-at behavior per sprite, so we can do with a single pair. This makes meta_cursor_sprite_prepare_at() inexpensive enough.
