Keep a copy of the name with the semaphore and move the export from the libkernel_sys stub into libkernel next to the other sem_* exports.

scePthreadMutexattrSetkind called NotImplemented_nid_no_patch for a kind
outside 1 to 4. Firmware 13.42's libkernel, run in an emulator, makes it
call pthread_mutexattr_setkind_np, which stores any kind as a signed
16-bit value and returns 0, and turns a null attribute's -1 with errno 22
into 0x8001FFFF. It now forwards to pthread_mutexattr_setkind_np and
converts the result with sceKernelError, so a null attribute or object
still returns 0x8001FFFF and now also sets errno 22.
An out-of-range kind is refused by scePthreadMutexInit with 0x80020016,
leaving the mutex untouched, as measured for the same module.
scePthreadMutexattrGetkind is unchanged; kind 0 now reaches it and
returns 0.
FreeBSD code reaches its thread pointer through %fs and macOS cannot set
the fs base. The macOS relinker turns each %fs access of a guest image
into a stub that reads the thread pointer from a pthread key and calls
Aps5GuestTlsAllocate on a thread's first access, registers the TLS
descriptor of an image with Aps5GuestTlsRegister, and routes
__tls_get_addr to Aps5GuestTlsGetAddr. No library provided them, so a
relinked executable could not start.
- Aps5GuestTlsRegister validates the descriptor the relinker wrote and
creates the key; its destructor frees the block of a thread.
- Aps5GuestTlsAllocateThreadPointer allocates the block (the TLS template
followed by zeros, then a 0x100-byte thread control block whose first
word points at itself, as on FreeBSD) and stores the thread pointer
under the key.
- Aps5GuestTlsAllocate is the entry the stubs call: rax holds the
descriptor and returns the thread pointer, every other register is
preserved, the upper halves of the ymm registers only where AVX exists.
- Aps5GuestTlsGetAddr returns the block of the thread plus the offset.

pthread_condattr_getclock threw for a null attribute pointer or a null
handle. FreeBSD 11.4 libthr (lib/libthr/thread/thr_condattr.c) returns
EINVAL for both before reading the clock, as setclock, setpshared,
getpshared and destroy here already do. A null output pointer with a
valid attribute faults on FreeBSD, so it still throws.
scePthreadCondInit ignores its name and nothing reads a condition variable name back, so pthread_cond_setname_np now only validates the condition variable and the name. Drops the stale libkernel_sys declaration and moves the debt entry to Silent stubs, citing shadPS4.

Store the name on the condition variable, creating a statically initialized one first, and return EINVAL for a destroyed one. A null cond or a null name throws, recorded in the libkernel debt file.

Main's #9573 implements scePthreadResume right after the
scePthreadMutexattrSetkind stub this branch removes from libkernel_sys;
the merge takes main's scePthreadResume and leaves the stub out.
Main's public-header audit wants one header declaration per export, so
the merge declares this branch's scePthreadMutexattrSetkind,
scePthreadMutexattrGetkind and pthread_rwlockattr_settype_np in
libkernel's Api.hpp, drops their stub declarations from libkernel_sys's
Api.hpp, has Mutex.cpp take sceKernelError from libkernel's Api.hpp,
and has the test include the libkernel headers instead of its own
declarations.
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.
