Chris Dalton 6ce447a4ec Eliminate mixed samples as an FBO type or AA type
From now on, sample counts always refer to the number of actual color
samples, and render targets don't have separate color and stencil
sample counts.

If mixed samples support is available when making a
"GrAAType::kCoverage" draw, then an op may attach and use a mixed
sampled stencil buffer internally. But this will all be invisible to
the client.

After this CL, we temporarily won't have a mode to use nvpr with mixed
samples. That will soon be fixed by a follow-on CL that enables nvpr
with mixed samples in the normal "gl" and "gles" configs.
