Fix DrawChoice() behaviour in wxRendererXP.

The implementation of wxRendererXP::DrawChoice() inadvertently used
wxRendererMSW::DrawComboBoxDropButton() and so drew the button in the classic
and not themed style.

Fix this by defining DrawChoice() in the base wxRendererMSWBase class and
reusing it in wxRendererXP via inheritance and not composition.

Closes #14337.
