This change fixes intermittent failures of the `core.smp_bind_affinity`
utest across SMP CI targets. The original failure was a flaky assertion on
unbound threads (`thread_inc[x] != thread_tic[x]` in thread_entry), not
incorrect bind_cpu behavior. CI logs already showed T0 binding worked
(thread_inc[0] == thread_tic[0] == 100) while the not_equal check failed.
The root issue is that unbound-thread CPU placement is platform-dependent
and outside the bind_cpu contract. On dual-core RISC-V/ARMv7 CI, an
unbound thread may legitimately run all iterations on core 0 while T0
delays on the same core, so any assertion requiring cross-core migration
(thread_inc != thread_tic, or core_mask with multiple bits) remains flaky.
This patch narrows the test to what bind_affinity actually verifies: T0
bound to core 0 must always execute on core 0. Unbound threads only add
scheduling pressure; their core_mask is printed for observation but not
asserted.
Changes:
- Sample `rt_hw_cpu_id()` and update counters under `rt_sched_lock` to
avoid migration skew between counting and CPU sampling.
- Track `thread_core_mask` for diagnostics; assert only T0 binding via
`thread_inc[0] == thread_tic[0]` and `thread_core_mask[0] == 1`.
- Remove flaky unbound-thread assertions (`thread_inc != thread_tic` and
multi-core core_mask checks).
- Move T0 assertions to the main test thread after all workers finish.
- Use atomic `finsh_flag`; reset counters and `threads[]` in `utest_tc_init`.
- Spin in worker loops after `run_num` until cleanup deletes them (do not
return from thread_entry or use `RT_WAITING_FOREVER` with `rt_thread_delay`).
- Guard `rt_thread_delete` in cleanup with non-NULL checks.

* [components][clock_time] Refactor time subsystem around clock_time
Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals.
Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional.
Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer.

Solution:
This patch adds the full, standardized documentation block to `sched_mtx_tc.c`, `sched_sem_tc.c`, `sched_thread_tc.c`, `sched_timed_mtx_tc.c` and `sched_timed_sem_tc.c` following the approved template.
The documentation details:
- Test Objectives and tested APIs
- Test Scenarios
- Verification Metrics
- Dependencies
- Test Execution command and Expected Results
This makes the test case's purpose and behavior immediately clear to future maintainers and reviewers.

Currently, the print information of this test case fails to demonstrate that
the high-priority thread has preempted the low-priority thread. This is because
when the high-priority thread prints the thread list, there is no information
about the low-priority thread (tlow), as tlow has already completed execution
and been destroyed. Therefore, the current execution logic cannot confirm the
successful completion of the preemption operation.
Solution: After the low-priority thread (tlow) releases the lock, add a busy-wait
loop while(!finish_flag);. At this point, when the high-priority thread (thigh)
prints the thread list information, tlow can be observed in the ready state, indicating
that it has been preempted by thigh.

In smp_assigned_idle_cores_tc, the finish_flag involves atomic operations
and thus requires address alignment.

Currently, this utest cannot determine whether threads are evenly distributed
across idle harts by observing the result of list_thread(). This is because
the presence of rt_thread_delay(5); causes all other threads to be in the
suspended state when thread information is printed. For example, if RT_CPUS_NR=4,
T0 executes list_thread() to print information, while T1~T3 are in hibernation
and thus it is impossible to observe which hart they are running on.
Solution:Here, the completion judgment condition has been modified. For example,
when RT_CPUS_NR=4, only RT_CPUS_NR-1 threads will be created (i.e., T0 to T2),
because running the utest occupies one hart. The execution is judged as completed
when finish_flag=0x0007, and the thread running the utest will call list_thread()
to print the information. Observe whether T0 to T2 are running on different
harts simultaneously.
