fs: remove watcher state errors for fs.watch

  • Remove ERR_FS_WATCHER_ALREADY_STARTED and
    ERR_FS_WATCHER_NOT_STARTED because those two situations should
    result in noop instead of errors for consistency with the
    documented behavior of fs.watchFile.
    This partially reverts fs: improve errors thrown from fs.watch() #19089
  • Update comments about this behavior.

fs: improve errors in watchFile and unwatchFile

  • Check if the watcher is active in JS land before
    invoking the binding, act as a noop if the state of
    the watcher does not match the expectation. This
    avoids firing 'stop' when the watcher is already
    stopped.
  • Update comments, validate more arguments and
    the type of the handle.
  • Handle the errors from uv_fs_poll_start
  • Create an IsActive helper method on StatWatcher
Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines
