Reimplement wxTextEntry::DoSetValue() in wxStyledTextCtrl.

The version inherited from the base class does work already but calling
Scintilla SetText() directly should be more efficient than selecting
everything and then calling ReplaceSelection() as the base class version does,
less code is executed.
