Fix user-defined signals drop by Darwin mprotect thread

When one user thread sets its own signal handler in multi-threaded
code, `GC-mprotect` thread may steal and drop user signal calls.
Because the thread does not know the user thread's signal handler, and
uses the default signal handler that ignores any signal call.
This becomes to drop the signal call.

* include/private/gc_priv.h [MPROTECT_VDB && DARWIN && THREADS
&& !NO_MARKER_SPECIAL_SIGMASK && !GC_NO_PTHREAD_SIGMASK]: Include
`signal.h` file.
* include/private/gc_priv.h [MPROTECT_VDB && DARWIN
&& !NO_MARKER_SPECIAL_SIGMASK] (GC_inner_pthread_sigmask): Declare as
function or define as a macro.
* os_dep.c [MPROTECT_VDB && DARWIN && NO_MARKER_SPECIAL_SIGMASK]
(create_detached_thread): Define `set` and `oldset` local variables;
call `sigfillset()`; call `GC_inner_pthread_sigmask()` around
`pthread_create`.
* pthread_support.c [MPROTECT_VDB && DARWIN && !GC_NO_PTHREAD_SIGMASK
&& NO_MARKER_SPECIAL_SIGMASK] (GC_inner_pthread_sigmask): Implement.
