[Core] Use the implementation method GetAddressOf in ValueObjectConstResultChild

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.
