Make ascii methods on u8 insta-stable
Those methods will shadow the methods of `AsciiExt`, so if we don't make them insta-stable, everyone will hitting stability errors. It is fine adding those as stable, because they are just being moved around [according to sfackler][1]. OPEN QUESTION: this commit also stabilizes the `AsciiExt` methods that were previously feature gated by the `ascii_ctype` feature. Maybe we don't want to stablilize those yet.
