SkPDF: remove all globally references SkPDFObjects
Move these singletons into SkPDFCanon (there is still a single object
per document; output PDF size will not change).
Motivation: After this change, all indirectly-referenced SkPDFObjects
are serialized exactly once. The next CL will add a memory saving
feature: a method to purge an object's resources immediately after
serialization. After that, further changes wil allow some objects to be
serialized *before* SkDocument::close(), leading to potentially very
large memory savings.
