CB-14224 Default.rd.xml updates (6.0.x patch)

Original issue

https://issues.apache.org/jira/browse/CB-14224

Platforms affected

Windows

What does this PR do?

Proposed template/Properties/Default.rd.xml updates in 6.0.x patch release, as rebased & squashed from #284:

• add MIT license text from https://github.com/Microsoft/Windows-universal-samples, with left aligment fixed
• add link to https://github.com/Microsoft/Windows-universal-samples/blob/master/SharedContent/cs/Default.rd.xml

As I said in #284 I think this is desired to satisfy the Apache RAT tool (used by coho audit-license-headers). Alternative may be to add an exception for this file but I think it would be better to follow the standard Apache procedure if possible.

What testing has been done on this change?

I verified that coho audit-license-headers -r windows with these changes does not show the missing license header any more.
