This pull request includes changes to the MetadataNode::SetInnerTypes method in the test-app/runtime/src/main/cpp/MetadataNode.cpp file to enhance the handling of inner types in V8.

Enhancements to inner type handling:

• Added a check to determine if a child is already defined as a function before setting it as an accessor. This prevents redefinition when the inner type is a companion object.
• Fixed the method to properly close the function scope with an additional closing brace.
