WebKit2: The CFNetwork Cache should be shared between the UI Process and the Web Process on Windows

[Jessie Berlin]

There is already code to share the CFNetwork Cache between the UI Process and the Web Process on Mac. We should do the same on Windows.

Having some comments above the items they apply to and some below confuses me!

It would be nice to match the order in which these are declared in the struct.

Ditto.

Presumably wkCopyFoundationCacheDirectory returns a CFStringRef, which you're leaking?

Removed the comment above the items it applied to, since it was not really helpful anyways.

Whoops! Fixed.
