Reland "Reland "Update SkCanvas' experimental SkiaRenderer API""
This reverts commit 138a06d1b1cd035daf6b6a970c75126e94777822.
Reason for revert: add explicit constructors to ImageSetEntry to account for the new arguments,
matching SkiaRenderer's current initializer list. Also hardens SkPictureDrawback's deserialization
code for drawEdgeAAImageSet and drawEdgeAAQuad from a fuzz that was found during the CL's brief
lifespan.
