Quit using shdocvw.dll(or ieframe.dll) in tests

[junkmd]

Internet Explorer will be end of support.
https://blogs.windows.com/windowsexperience/2021/05/19/the-future-of-internet-explorer-on-windows-10-is-in-microsoft-edge/

Currently, some tests using IE were skipped, (see #267 (comment) by @dmwyatt, #271, #298)

However, there still remains tests using shdocvw.dll(ieframe.dll), which provides IE and web browser classes.
This will likely cause us to inadvertently use the IE class.

To be samples for testing, there is no need to use the DLL, and we plan to replace it with something more universal.

This issue contains restoring tests using InternetExplorer and have been skipped.

        self.assertTrue(isinstance(obj, UIAutomationClient.IUIAutomation))

In most cases, I believe that testing the behavior of COM object methods is unnecessary.
When testing methods, including their behavior, we should try them on more primitive objects (such as Scripting.IDictionary) rather than on objects with more complex necessary conditions (such as UIAutomationClient.CUIAutomation and some
web browser).

we should try them on more primitive objects
