Add SeL4Debug component to expose sel4 debug syscalls.

Browse Source 
- add a SeL4Debug component that wraps seL4DebugPutString and seL4DumpScheduler
  system calls that are marked static inline (so not callable from rust)
- connect seL4Debug to the DebugConsole and add a "ps" command to the shell
  that uses sel4DumpScheduler to print the tcb's on the console; e.g.

KATA_PROMPT> ps
Dumping all tcbs!
