Implement codegen for bound class reference expressions

- Inline the usage of ExpressionCodegen#generateClassLiteralReference into
  ClosureCodegen, simplify
- Support DoubleColonLHS.Expression in generateClassLiteralReference
- Substantially simplify KClass.java intrinsic by reusing
  generateClassLiteralReference
