Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Since pthread_mutex is implemented by sem, it is impossible to see in ps who holds the lock and causes the wait.
Replace sem with mutex implementation to solve the above problems

NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

The "p" format specifier already prepends the pointer address with
"0x" when printing.

pthread_condclockwait() can not distinguish between interrupt and timeout,
which cause these API not follow POSIX:
pthread_rwlock_timedrdlock()
pthread_rwlock_timedwrlock()
pthread_condtimedwait()
POSIX:
Upon return from the signal handler the thread resumes waiting for
the condition variable as if it wasnot interrupted
These functions shall not return an error code of [EINTR].
Replacing nxsem_wait() with nxsem_clockwait_uninterruptible() can solve it.

There is a potential problem that can lead to deadlock at
condition wait, if the timeout of watchdog is a very small value
(1 tick ?), the timer interrupt will come before the nxsem_wait()

Summary:
- I found potential bugs in pthread_condclockwait.c
- Actually, sched_unlock() and wd_cancel() were misplaced.
- This commit fixes this issue
Impact:
- pthread_cond_clockwait() only
Testing:
- Tested with ostest with the following configs
- sabre-6quad:nsh, sabre-6quad:smp, sim:ostest
