[libcpu/arm64] feat: Trimming General Context This patch focuses on the ARM64 general context handling code. The modifications are aimed at enhancing performance by simplifying context save/restore operations. Changes include: - Adjusted stack alignment in `arch_set_thread_context` function. - Updated `lwp_gcc.S` to reset frame pointer and link register. - Refined `rt_hw_backtrace_frame_unwind` to handle user space address checks. - Added `GET_THREAD_SELF` macro in `asm-generic.h`. - Simplified context saving/restoring in `context_gcc.h` and related files. - Optimized `rt_hw_context_switch_interrupt` and related assembly routines.
