Changes finaliseCap to return a generic definition of cleanup information that needs to be done, instead of just encoding an IRQ number. The post deletion information is encoded as a `cap_t` due to the capability type already being a union of all the possible information. Aside from providing a properly generic mechanism the motivation is to support a similar cleanup phase for I/O ports in the future.
