Revert "Redefine the meaning of sample counts in GPU backend."
This reverts commit 48825b11ad25c98b9a4884d5cc0edd4e290c4409.
Reason for revert: nanobench
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.
