MINOR: debug: do not statify a few debugging functions often used with wdt/dbg

A few functions are used when debugging debug signals and watchdog, but
being static, they're not resolved and are hard to spot in dumps, and
they appear as any random other function plus an offset. Let's just not
mark them static anymore, it only hurts:
  - cli_io_handler_show_threads()
  - debug_run_cli_deadlock()
  - debug_parse_cli_loop()
  - debug_parse_cli_panic()
