Merge branch 'wxlistctrl-fixes'

Improve consistency of checkboxes in wxListCtrl between virtual and
report mode, and between the generic and MSW implementation, see #23869.

Also disable WS_EX_COMPOSITED for virtual wxListCtrl because it
generates an endless stream of cache events, see #23878.

See #23890.
