This will enable more parts of Chromium to use PA, and will make it easier for things outside of Chromium (e.g. PDFium) to use PA. This change is intended to be merely a move, and should not have significant performance impact. This moves only the core of PA; higher API layers that Blink uses to call into PA remain in Blink.
