[Core] Use the implementation method `GetAddressOf` in `ValueObjectConstResultChild`

[aleksandr.urakov]

Summary

This patch allows to retrieve an address object for ValueObject's children retrieved through e.g. GetChildAtIndex or GetChildMemberWithName. It just uses the corresponding method of the implementation object m_impl to achieve that.
