[PDF] Make stream compression optional on a per device basis.
There are a lot of small pieces to make this change work:
- SkPDFDocument (and SkPDFCatalog) take flags to disable compression (and font embedding - not implemented yet, can disable font subsetting for now).
- SkPDFStream now defers compression until the size/emit step.
- Classes that *had* a stream (because they didn't know the stream size at construction time) now *are* streams to make the substitution work correctly.
- The SkPDFShader implementation got pulled apart into two classes, one that is a SkPDFDict, and one that is a SkPDFStream (making the common ancestor SkPDFObject).
- Added helper methods in SkPDFObject for children that have simple resource lists.
- Added an iterator to SkPDFDict so that a substitute SkPDFStream can get a copy of the stream dictionary.
- Change SkPDFDocument to have a pointer to an SkPDFCatalog to remove a new circular header reference.
