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.
