Check that rows in wxDataViewListCtrl have the right size

Browse Source 
Vectors passed to wxDataViewListCtrl::{Append,Insert,Prepend}Item()
functions must have the correct, i.e. equal to the column count, number
of items as otherwise accessing them later would result in a crash.

Add checks verifying that this is indeed the case.

Closes https://github.com/wxWidgets/wxWidgets/pull/724
