Win11 fixes

[jacob-ewald]

Microsoft has changed how certain controls behave and it seems to be dependent on both .Net version and OS version. The changes here are intended for .Net 4.8 and Windows 11.

• Combo boxes now only implement the invoke and expand/collapse patterns until it's expanded. Once opened, the selection pattern should be available after finding the ComboLBox child control.
• Table headers are now nested underneath a table header control that contains all of the headers as direct children
• A combo_box is no longer synonymous with a select_list since that control type seems to be more for list boxes or tree views
• Certain menus need to be opened in order to enumerate their child menu items
