elexis 3d07327837 Introduce a JSInterface_IGUITextOwner to encapsulate JSI_IGUIObject::getTextSize from 9c5062147a / D844.
JSI_IGUIObject should not contain functions that work only for some GUI
Object types, refs #5442.

Deduplicate the shuffled copy of CText::SetupText.

Avoid the 80 times slower dynamic_cast mandated by the virtual class
inheritance by adding an ugly overridable pointer to the base class
pointing at this derived classes, as bargained with Vladislav and
proposed by wraitii in D1781 id=8426.
This may be improved by refactoring the IGUIObject and JSInterface
classes to use templates and / or eliminating its virtual inheritance.

Implement and use FromJSVal / ToJSVal CSize specialization.
Remove the JS::CallArgsFromVp call.
