Add Third-Party code in qregion.cpp to qt_attribution.json file

This makes it visible also in the overview documentation of the module,
and can be used to automatically generate attribution documents.

The code actually mentions the names and file versions (CVS?) where things
got copied from; however, X11 seems to have stopped using CVS a long time
ago, and without a server it's hard to determine the exact X11 version that
was copied from. It arguably doesn't matter, anyhow, because we won't update
the code anymore.
