Normalize Interpreter

Summary:
Finally we just need to normalize the core interpreter. This adds one new set of metadata which is a feature set - these are effectively identical to the recent `PREPROCESSOR_FLAGS` that alexmalyshev has been adding (although we don't yet generate the pre-processor flags from them).

Instead they're being used to map the differences between the core differences we have between 3.10 and 3.12. These include special 3.10 eval loop, shadowcode, shadow frames, and the 3.12+ JIT generator implementation.
