Debugger: Split into core library and application.

- Add subfolder src/kits/debugger which contains the debugger's core
  functionality and lower layers. Correspondingly add headers/private/debugger
  for shared headers to be used by clients such as the Debugger application
  and eventual remote_debug_server. Adjust various files to account for
  differences as a result of the split and moves.
- Add libdebugger.so to minimal Jamfile.
