[ddc] Clarify class vs type references for records
Preparation for separating type representation from classes. Use `JS_CLASS_REF(_RecordImpl)` to inline a reference to the class in JavaScript (not the type representation). Use a standard Dart `is _RecordImpl` type test and let the compiler produce the correct type test code.
