Revert of SkFontData to use smart pointers. (patchset #3 id:40001 of https://codereview.chromium.org/2339273002/ )

Reason for revert:
Killing Mac

Original issue's description:
> SkFontData to use smart pointers.
>
> The SkFontData type is not exposed externally, so any method which uses
> it can be updated to use smart pointers without affecting external
> users. Updating this first will make updating the public API much
> easier.
>
> This also updates SkStreamAsset* SkStream::NewFromFile(const char*) to
> std::unique_ptr<SkStreamAsset> SkStream::MakeFromFile(const char*). It
> appears that no one outside Skia is currently using SkStream::NewfromFile
> so this is a good time to update it as well.
