… and use it (#22791) The following is duplicated across codegen, formatter (and potentially linter in future): ```rust match self { Self::With => "with", Self::Assert => "assert", } ``` This PR adds `WithClauseKeyword::as_str` method to centralize stringifying this attribute. `as_str` aligns with the other helpers such as `VariableDeclarationKind::as_str()`, `ImportPhase::as_str()`, `TSAccessibility::as_str()`, and `TSModuleDeclarationKind::as_str()`. Operators in `oxc_syntax` also have the same `as_str` methods.
