* [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.
