Subject: [PATCH] perf(linter): reduce indirection (#13574)

Follow-on after #13138, as per [this comment](https://github.com/oxc-project/oxc/pull/13138#discussion_r2328531176).

Previously `rules_by_ast_type` and `rules_any_ast_type` contained `&&RuleEnum`, which is unnecessary indirection. Store `&RuleEnum` instead.
