Fix g++ builds by avoiding early HeapSupplement<Document> instantiation.
Building ToT with g++ (component build) currently breaks when using
the Oilpan type HeapSupplement<Document>:
...
error: type attributes ignored after type is already defined [-Werror=attributes]
...
.../dom/Document.h:179:51: note: in expansion of macro ‘WillBeHeapSupplement’
extern template class CORE_EXTERN_TEMPLATE_EXPORT WillBeHeapSupplement<Document>;
It appears that g++ cannot be kept happy if it implicitly instantiates
a template at a type and then later sees an extern decl like the above
with some extra attributes attached.
Hence, bring the required types into scope for FontFaceSet's declaration
to avoid that unfortunate situation.
