In SkGPipe, only serialize SkTypefaces in cross process mode.

Also make SkGPipeController ref the recording canvas to ensure that
objects used by SkGPipeCanvas (e.g. SharedHeap and fTypefaceSet, which
hold references to objects to which pointers are written to the stream)
survive to be played back even if SkGPipeWriter.endRecording() is called.
