Greg Daniel d358cbebd4 Add support for plumbing GrDstSampleType through Ops and Pipeline creation. 
This CL adds a new type GrDstSampleType to say how we will sample the dst.

We add tracking of the GrDstSampleType in the recording of GrOps and
then during execution passing the information along to the GrPipeline.

In general the tracking of GrDstSampleType is a global state of a GrOpsTask
so it is kept separate fro the DstProxyView which is more specific to a
single Op on the GrOpsTask.
