* [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.

In this patch, a hook list has been introduced to address the concerns
regarding coupling issues arising from modifications to the serial code
for integrating TTY logic.
Signed-off-by: Shell <smokewood@qq.com>
This option is for RT-Thread Nano version.
If select this option, it will not compile components/libc
folder and only use tool chain internal libc. Normally, the
tool chain internal is only cover ISO standard (e.g. armcc),
but some tool chains' internal libc will cover more than
ISO standard (e.g. newlib).
