* [libcpu] arm64: Add hardware thread_self support
This patch introduces hardware-based thread self-identification
for the AArch64 architecture. It optimizes thread management by
using hardware registers to store and access the current thread's
pointer, reducing overhead and improving overall performance.
Changes include:
- Added `ARCH_USING_HW_THREAD_SELF` configuration option.
- Modified `rtdef.h`, `rtsched.h` to conditionally include
`critical_switch_flag` based on the new config.
- Updated context management in `context_gcc.S`, `cpuport.h`
to support hardware-based thread self.
- Enhanced `scheduler_mp.c` and `thread.c` to leverage the new
hardware thread self feature.
These modifications ensure better scheduling and thread handling,
particularly in multi-core environments, by minimizing the
software overhead associated with thread management.

* fixup: address suggestion
* fixup: rt_current_thread as global
* scheduler: add cpu object for UP scheduler
Also, maintain the rt_current_thread in cpu object on UP scheduler.

* [libcpu/arm64] add C11 atomic ticket spinlock
Replace the former implementation of flag-based spinlock which is unfair
Besides, C11 atomic implementation is more readable (it's C anyway),
and maintainable. Cause toolchain can use their builtin optimization and
tune for different micro-architectures. For example armv8.5 introduces a
better instruction. The compiler can help with that when it knows your
target platform in support of it.

* [thread] Add rt_thread_close()
This patch introduces a new function `rt_thread_close()` to enhances the
usability and maintainability by providing a dedicated mechanism for
closing threads.
- A new function `rt_thread_close()` is added to the API, providing a
standardized approach for closing threads.
- The `rt_thread_close()` function removes a thread from the thread
queue, updates its status to indicate closure, and performs the thread
timer detaching which is a embedded timer in thread object.
- Additionally, the `rt_thread_detach()` function is modified to utilize
`rt_thread_close()` internally, streamlining the thread detachment
process.

When we create thread A by rt_thread_init but do
not init the thread object,and then create thread
B in the thread A,it maybe crash.
