This reverts commit 48825b11ad.

Original change's description:
> Redefine the meaning of sample counts in GPU backend.
>
> Old: 0 -> nonMSAA
> 1+ -> MSAA
>
> New:
> 0 -> error/unsupported
> 1 -> nonMSAA
> 2+ -> MSAA
>
> We still allow 0 to mean nonMSAA in three sets of public APIs for backwards compatibility:
>
> 1) SkSurface factories
> 2) GrBackendRenderTarget constructors
> 3) GrCaps::getSampleCnt()'s requestedCount parameter
>
> However, we immediately clamp to 1 and treat 0 as invalid/non-renderable internally.
>
> This also changes the behavior when using a large sample count. We now fail in that case rather than using the largest sample available sample count. GrCaps::getSampleCount() will return 0 in this case.

Old: 0 -> nonMSAA
1+ -> MSAA
New:
0 -> error/unsupported
1 -> nonMSAA
2+ -> MSAA
We still allow 0 to mean nonMSAA in three sets of public APIs for backwards compatibility:
1) SkSurface factories
2) GrBackendRenderTarget constructors
3) GrCaps::getSampleCnt()'s requestedCount parameter
However, we immediately clamp to 1 and treat 0 as invalid/non-renderable internally.
This also changes the behavior when using a large sample count. We now fail in that case rather than using the largest sample available sample count. GrCaps::getSampleCount() will return 0 in this case.

This CL mainly just:
stores the GrContextOptions in GrContextThreadSafeProxy (so they can be passed on to a stubbed out GrContext)
adds a method to create a stubbed out GrContext that has a GrStubGpu
- the stubbed out GrContext isn't quite ready for prime time yet
