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.
