Series [v4] sys/lock.h: Add clock selection APIs for the synchronization object class |

Commit Message

Mazen Adel Elmessady March 5, 2026, 6:33 p.m. UTC 
  Updated _Semaphore_Wait_timed (which is currently unused in RTEMS)
to _Semaphore_Wait_timed_clock which
to be used in RTEMS sempahore API.
This will ease the support of the new clock
functions added in Posix Issue 8.

V2: Kept _Semaphore_Wait_timed while adding
_Semaphore_Wait_timed_clock

V3: Added _Mutex_Acquire_timed_clock()
_Mutex_recursive_Acquire_timed_clock()
_Condition_Wait_timed_clock()
_Condition_Wait_recursive_timed_clock()
To include all the clock selection APIs for
all of the synchronization object class

V4: Fixed formatting and removed the
forward declaration of struct timespec
