Fixed best sizes for wxUniv controls.

Many wxUniv controls had a way too small best size which was noticeable when running e.g. the widgets sample. Regression started in r61169 where wxWindowBase::DoGetClientBestSize() was introduced but that virtual function already existed in wxUniv's wxWindow. Removing wxUniv's wxWindow::DoGetBestSize and wxWindow::DoGetBestClientSize fixes sizing issues.
