tracepoints: Add check trace callback type
This check is meant to be used by tracepoint users which do a direct cast of
callbacks to (void *) for direct registration, thus bypassing the
register_trace_##name and unregister_trace_##name checks.
This permits to ensure that the callback type matches the function type at the
call site, but without generating any code.
