LoongArch: Add STACKTRACE support
1. Use common arch_stack_walk() infrastructure to avoid duplicated code
and avoid taking care of the stack storage and filtering.
2. Add sched_ra (means sched return address) and sched_cfa (means sched
call frame address) to thread_info, and store them in switch_to().
3. Add __get_wchan() implementation.
Now we can print the process stack and wait channel by cat /proc/*/stack
and /proc/*/wchan.
