* [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.

- 为RT-Thread设计MPU抽象层,支持ARMV7-M,ARMV8-M架构,让用户使用MPU检测栈溢出等内存问题,实现线程内存隔离
- 在components/mp目录下提供通用的API,libcpu目录下提供各处理器架构的具体实现
- 在STM32U575 NUCLEO, STM32H75 NUCLEO开发板测试通过

warnings in Doxygen.
将Doxygen输入文件(由Doxyfile中的INPUT定义)中的失效Doxygen分组指令(如/*@*/和/*@}*/)更改为有效的分组指令(如/**@*/和/**@}*/);(此处只对INPUT中的文件做了修改,bsp目录下和libcpu目录下存在近万个失效的Doxygen分组指令,但由于不作为文档的输入文件且这些文件过于庞大老旧,没有对这些文件中的无效指令做修改)
将图片文件统一放入了images目录下;
修改了Doxyfile和部分Doxygen注释,使得Doxyfile能够定位到新的代码路径且不受重复实现的影响;
解决了一些注释中的参数名不匹配、参数多余/缺失等问题。
