This introduces some code to convert from V8's test JSON output to JUnit
XML. We need this because V8's latest refactor of their test runner has
made it difficult to float our JUnit reporter patch on top (see the
referenced issue).
I also think that there needs to be the same changes to vcbuild.bat, but
I don't know how to do test those yet. I can create a Windows VM and
test it if we decide to go with this approach.
