Revert of Switch SkPDFStream's internal storage from SkStream to SkData (https://codereview.chromium.org/340783013/)
Reason for revert:
Causes canary failures
Original issue's description:
> Switch SkPDFStream's internal storage from SkStream to SkData
>
> Motivation: This makes SkPDFStream thread-safe for two threads
> serializing it at once, since a SkStream has an internal position.
>
> Updated SkPDFFont, SkPDFGraphicState, and SkPDFPage's use of
> SkPDFStream to use the SkData constructor rather than the SkStream
> constructor (saving a memcpy).
