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

On Windows a DLL is only loaded when the executable imports from it. The
thread test imported nothing from libkernel, so its load-time registration
never ran and _Tss_create threw. Comparing _Thrd_current with
scePthreadSelf imports libkernel and checks the forward.

The console's std::__sce_v2::_Throw_Cpp_error raises a
std::__sce_v2::system_error, not the unversioned std::system_error this
forwarded to. It moves to the versioned exception change, which adds that
type.
Review on #8885: the versioned unlock, wait, signal and broadcast calls
return 0 whatever the kernel returns, as the console's do (each calls the
kernel and clears eax). The test now shows the kernel failing an unowned
unlock and wait while the wrappers report success.

The versioned Dinkumware entries operate on libkernel's own mutex,
condition and thread handles: _Mtx_init(_with_name), _Mtx_destroy,
_Mtx_lock, _Mtx_trylock, _Mtx_unlock, _Cnd_init(_with_name),
_Cnd_destroy, _Cnd_wait, _Cnd_signal, _Cnd_broadcast, _Thrd_detach,
_Thrd_join, _Thrd_yield, _Thrd_id and _Throw_Cpp_error. libkernel
registers the pthread calls with libc next to the C11 forwards.

_Call_once, _Tss_create, _Tss_delete, _Tss_get, _Tss_set, _Thrd_equal,
_Thrd_current and _Thrd_exit call scePthreadOnce, scePthreadKeyCreate,
scePthreadKeyDelete, scePthreadGetspecific, scePthreadSetspecific,
scePthreadEqual, scePthreadSelf and scePthreadExit and return their
results unchanged, as the console's libSceLibcInternal does.
_Mtx_current_owns returns 1 there. libkernel registers the calls with
libc at load, next to the pthread_create registration.

Animal Well (PPSA22520) imports _Thrd_detach (L7f7zYwBvZA) from libc.prx and nothing exports it, so the Windows loader stops at startup. Register libkernel's pthread_detach with libc like pthread_create and pthread_join, and return _Thrd_error (4) when it fails.
