This patch aims to split the implementation details of FontFace(Set) into FontFace(Set)Impl classes. The Impl variants have threadsafe refcounting and are intended to be the basis for worker support for FontFace(Set). We need threadsafe objects to pass around because parts of the stack can only run on the main thread (network loading of font data, graphics initialization of a font) even if the FontFace(Set) itself lives on a DOM worker thread. Given the DOM facing objects are cycle collected, we need additional indirection to support this use case. This patch should be a non-functional change.
