add: Stat polling support while `fs.watch` doesn't work.

Add a new cli option: -g --polling [SPAN]

    If state polling mode is enabled, use it.
    Else use the native api.

    This is useful while watching remote directory.
    Such as the `fs.watch` won't catch the SMB server's file change event.
mov: Change the option name `--polling` to `--watch-polling`, and only leaves the long option name.
opt: Optimize the comment of the `--watch-polling` option.
fix: `opts.polling` changed to `opts[watch-polling]`
Cleanup and extend `METHOD_DEF`

  * Fixes #2949: Detect reserved names (not only for instance methods)
  * Don't assign names which might result in incorrect `super` calls
Fixes #3232 -- Tag all class properties `static`

(and remove duplicate `context` assigment)
