fix(es/typescript): Fold ambient const and ambient enum members `tsc` treats `declare const x = 1` and members of `declare enum` that have constant initializers as constant enum expressions, while erasing the declarations themselves. The collection pass skipped everything ambient, so both stayed opaque and the following auto-incremented members collapsed to `undefined`. Ambient consts now populate `const_vars` like any other const. Ambient enum members go to a separate `ambient_enum_record` that only the evaluator consults: `tsc` folds them inside enum and const initializers but never rewrites runtime reads of the ambient object, and the inliner keys on `enum_record` membership. There is no auto-increment in ambient enums — a member without an initializer stays opaque, matching `tsc`.
