Throw error on unexpected positional arguments (#130274)

Browse Source 
This PR fixes ignoring when random positional arguments added to the
`flutter gen-l10n`.

So we are no longer able to call `flutter gen-l10n hello world` or
`flutter gen-l10n --format false`.

Fixes https://github.com/flutter/flutter/issues/118203
