Updated the docking window container UIA hierarchy to better support Coded UI Test.
Updated clicks on auto-hide tabs to focus the tab prior to opening/closing the auto-hide popup.
Added the DockSite.AutoHidePopupClosesOnLostFocus property that can be temporarily set to false to prevent an auto-hide tool window's popup from closing while a dialog is displayed.
Improved the logic when dragging over linked nested dock sites such that a dock host in the same dock site will be targeted by default. If the Shift modifier key is pressed, an alternate child/parent dock site's dock host that intersects the same location can be targeted.
Improved interop focus handling logic.

Updated the Today button to disable when today's date is not selectable.
