Use SIGSYS to suspend thread on Hurd, FreeBSD, RTEMS if built with TSan
Also, support GC_USESIGRT_SIGNALS and SUSPEND_HANDLER_NO_CONTEXT
macros properly on the entitled platforms.
* include/private/gc_priv.h [SIGNAL_BASED_STOP_WORLD && !SIG_SUSPEND
&& !THREAD_SANITIZER && !GC_LINUX_THREADS && !GC_DGUX386_THREADS
&& !GC_USESIGRT_SIGNALS && (GC_FREEBSD_THREADS || HURD || RTEMS)]
(SIG_SUSPEND): Define to SIGUSR1 (or 32+6).

|| ALPHA || AARCH64 || ARM32 || X86_64 || RISCV) && FREEBSD
|| I386 && (RTEMS || HURD)] (SIG_SUSPEND, SIG_THR_RESTART): Remove.

&& !GC_HPUX_THREADS && !GC_OSF1_THREADS && !GC_NETBSD_THREADS
&& !GC_USESIGRT_SIGNALS && (GC_FREEBSD_THREADS || HURD || RTEMS)]
