Price enum case values through InitializerExprTypeResolver in EnumSanityRule

The rule fires on InClassNode before the enum body is walked; case values
are initializer expressions, so the initializer resolver (already used by
the not-backed-enum message) is the right source - not Scope::getType()
on the yet-unprocessed node.
