Implement pthread_attr_setcreatesuspend_np, pthread_resume_np,
pthread_resume_all_np and pthread_multi_np with the sce forms
scePthreadAttrSetcreatesuspend, scePthreadResume, scePthreadResumeAll
and scePthreadMulti, following FreeBSD 11.4 libthr and the firmware
13.42 libkernel_sys module. A thread created suspended waits before its
start routine, outside any cancellation point, until it is resumed.
sceKernelRaiseException throws on Windows for a thread still suspended
at creation.
scePthreadMutexTimedlock on a mutex the caller holds, and
scePthreadRwlockTimedrdlock and scePthreadRwlockTimedwrlock on a rwlock
it holds for writing, returned EDEADLK at once. The console returns
ETIMEDOUT, as the prosper console oracle measured. They now sleep until
the timeout and return ETIMEDOUT, as FreeBSD libthr does. The POSIX
timed locks call these and change with them.

Kept both sides of GuestLibcThreads.cpp: main's ThreadHelpers test and this PR's VersionedSync test, both called from main().

scePthreadCreate returns ENAMETOOLONG for a name of 32 bytes or more without creating the thread, and scePthreadDetach returns ESRCH for a joined thread.

scePthreadRwlockattrSettype stored any type and threw on a null
attribute. Measured against firmware 13.42's libkernel by BunnyFl in
#9632, it is the same function as pthread_rwlockattr_settype_np with
the error converted to an SCE code: types 1 and 2 are stored and return
0, and any other type, 0 included, or a null attribute or object
returns SCE_KERNEL_ERROR_EINVAL and stores nothing.
#9272 keeps liveStacks and protectedStackPages alive through static
destruction so that a late mprotect from an atexit handler can still
look up guest thread stacks. The mutex guarding them is still a static
std::mutex. libstdc++'s std::mutex has a trivial destructor, so it keeps
working on Linux, but libc++ destroys the pthread mutex, and a later lock
throws "mutex lock failed: Invalid argument": on macOS the exit probe of
guest_memory_lifetime fails at its mapping protection stage. The lock is
now allocated and never destroyed, like the maps.
The same change is part of #7201 and #8658.

FreeBSD 11 libthr's pthread_condattr_setclock returns EINVAL for any clock
other than CLOCK_REALTIME, CLOCK_VIRTUAL, CLOCK_PROF and CLOCK_MONOTONIC.
scePthreadCondattrSetclock stored any clock id; it now answers
SCE_KERNEL_ERROR_EINVAL for the others, and pthread_condattr_setclock
EINVAL through it.
liveStacks, protectedStackPages and guestStackMappings were plain
globals, so libkernel's static destructors freed them at exit while
detached threads could still unregister their stacks or look one up.
ThreadSanitizer reports the race in guest_pthread_join_detach: the main
thread's static destruction of liveStacks against a detached thread's
UnregisterStack under stackLock. The maps are now created once and
never destroyed, as Apr.cpp does for its globals.

Both were missing from libkernel.prx, so a title importing either
(dYv-+If2GPk, RRnSj8h8VR4) failed to load. They take a relative timeout
in microseconds and are scePthreadRwlockTimedrdlock and
scePthreadRwlockTimedwrlock with POSIX error numbers; a zero lock is
initialized as by pthread_rwlock_rdlock. The signature comes from
shadPS4, which registers one function for each NID and its
scePthreadRwlockTimed* twin; FreeBSD 11.4 has no such calls. The throwing
libkernel_sys copies are removed, as an export may live in one library
only. Recorded in the libkernel debt file.
