This patch improves the atomicity of context switching by ensuring that the stack pointer (sp) and thread self updates occur simultaneously. This enhancement is crucial for maintaining thread safety and preventing potential inconsistencies during context switches. Changes: - Modified `cpuport.h` to use `ARM64_THREAD_REG` for thread self access. - Added an `update_tidr` macro in `context_gcc.S` to streamline thread ID updates. - Adjusted `rt_hw_context_switch_to` and `rt_hw_context_switch` to call `update_tidr`, ensuring atomic updates during context switches. - Cleaned up `scheduler_mp.c` by removing redundant thread self assignments.
