Define unambiguous Is{List,Text}Empty() in wxOwnerDrawnComboBox.

Like in wxComboBox itself, it's useful to provide these methods to avoid
problems with ambiguous IsEmpty(), inherited from both wxTextEntry and
wxItemContainer.

Closes #16618.

IsEmpty() is not available in this class.
This method is documented here only to notice that it can't be used
with this class because of the ambiguity between the methods with the
same name inherited from wxItemContainer and wxTextEntry base classes.
Because of this, any attempt to call it results in a compilation error
and you should use either IsListEmpty() or IsTextEmpty() depending on
what exactly do you want to test.
