Remove unnecessary dynamic cast in wxComboPopupWindow.

Objects of this type are either always of wxPopupTransientWindow type, in
which case just a static_cast<> is enough and we don't need a dynamic one, or
is never of its type in which case this code shouldn't be compiled and if it
is, then static_cast<> will correctly fail preventing it from compiling.
