Moved more code from wxDataViewCtrl to wxDataViewCtrlInternal.

Add new special API for wxDataViewVirtualIndexModel::Reset() as
wxDataViewModel::Clear is something different and needs a different, two
step API under GTK+, one for destroying the current view and one for
rereading the new contents.
Added ::BeforeReset() and ::AfterReset() notifications for that purpose.
