This patch updates the core reflection for the new language model for inline classes.

- `Class::isInlineClass` returns true for inline classes
- `Class::valueType` returns the value projection of an inline class
- `Class::referenceType` returns the reference projection if it's an inline class,
    or this class if it's not an inline class

If this class has no val type or ref type, `Class::valueType` and `Class::referenceType`
return an empty `Optional`.   We can re-examine  if we should modernize Class API shape
where  we can rather than holding to the tradition.

I updated TestIntrinsics.java to use the new APIs for now to keep it compiled.
This test will be updated when the intrinsification of the old API `Class::asPrimaryType`
and `Class:asIndirectType` is removed.
