Joyee Cheung 78bbee385b debugger: add --help to node inspect and improve docs ...

- Add `--help` / `-h` to `node inspect` covering both interactive and
  non-interactive probe modes. The help text is printed when
  `--help`/`-h` appears before any positional argument to avoid
  hijacking `--help` passed to a child script.
- Improve the documentation of probe mode and add examples, explain
  same-location probe coalescing, TDZ caveat for let/const bindings,
  basename matching and exit code behavior. Also move it to a
  section parallel to interactive mode. Remove recommendation of
  evaluating structured expressions as that is prone to missing
  info in JSON mode.

Drive-by: When probe mode exits due to invalid arguments, exit with
`kInvalidCommandLineArgument` (9) instead of `kGenericUserError` (1).
