take gr-context parameter to refEncoded, indicating a desire for only gpu-specific formats

Prime motivator:
- we always call refEncoded on the generator when trying to upload
   - we call it *before* we ask for raster or YUV
- for blink, this call can be very slow, as they have to cons-up their SkData the first time (and grab a mutex to do it)
- this parameter will indicate to them that we're only interested in gpu formats, which they will know if they have.
