Subject: [PATCH] Dock: Replace IsShownInSwitchers with
 HiddenOwnerWindowBehavior in DockWindow (#45839)

## Summary of the Pull Request

This PR replaces the use of the property AppWindow.IsShownInSwitchers,
which requires a running explorer.exe instance, with
HiddenOwnerWindowBehavior. This behavior is used by MainWindow and
ToastWindow to hide the window by utilizing both the Tool Window style
and a safely invoked IsShownInSwitchers.
