RT_USING_STDC_ATOMIC is a user selected option on current config system.
While the RT_USING_HW_ATOMIC is a forced option selected by Kconfig
under libcpu. And the RT_USING_STDC_ATOMIC will be meaningless if we set
RT_USING_HW_ATOMIC to first priority if the arch has hw-atomic.
Changes:
- set RT_USING_STDC_ATOMIC to first priority on rttypes.h

* [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.

* [src] add rt_hw_cpu_id() wrapper API
rt_hw_cpu_id() is an unsafe API which should not be used by most codes
directly. It's error-prone because it must be used in proper context,
otherwise it can lead to errors and unpredictable behavior.
This patch adds a wrapper API for rt_hw_cpu_id() to address this risk.
It includes the context-checking functionality and provides a safer
alternative for obtaining CPU IDs, ensuring that it is used correctly
within the appropriate context.

* [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.
