Add a simple manual test for loading Active X controls.

Add a simple Ax Viewer console application that can be passed
a CLSID on the command line with options to dump the widget/
window hierarchies using diaglib.
Debugging it is easier than debugging testcon, which is also a server
that cannot be built as console application.
