Improve HitTest in generic wxListCtrl

Browse Source 
Detect when a checkbox is hit and return wxLIST_HITTEST_ONITEMSTATEICON.

Determine the correct location of the icon, it might be preceded by a
checkbox.

Return only the icon rectangle in GetSubItemRect with wxLIST_RECT_ICON,
not the padding or margins above/below the icon.

Closes #25764.
