fix(linter): allow whitespace control characters in no-control-regex (#6140)

- fixes https://github.com/oxc-project/oxc/issues/6136

The original eslint rule checks if chars start with `\u` or `\x`, but our character spans are currently busted and only report 1 char for chars like `\u{0a}`. I've made whitespace an exception to the rule, so we don't report `\x0a` currently, which is fine for now I think
