wxWidgets/include/wx/combobox.h
Vadim Zeitlin 2970f22a89 Include <wx/textctrl.h> from <wx/combobox.h> for compatibility.
The wxComboBox header itself doesn't need <wx/textctrl.h> but there exists
code using wxComboBox with wxTextCtrl styles and events that doesn't include
<wx/textctrl.h> explicitly because it wasn't necessary in 2.8. So include it
from wx/combobox.h to avoid breaking this code after an upgrade to 2.9.

Closes #14132.
