[PULL 17/17] system/runstate: Document qemu_add_vm_change_state_handler_prio* in hdr

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Generally APIs to the rest of QEMU should be documented in the headers.
Comments on individual functions or internal details are fine to live
in the C files. Make qemu_add_vm_change_state_handler_prio[_full]()
docstrings consistent by moving them from source to header.
