Avoid using very large wxDC origin offsets with wxGenericListCtrl

Using the wxDC origin to implement scrolled drawing can require very large
origin offsets, which can exceed Cairo coordinate limits (2^23), and therefore
currently wxGTK3 limits as well. Managing the scroll offsets turns out to be
pretty simple in this case, avoiding any coordinate limitations.
See #25365
