Always attach stencil buffers with exact sample count matches

After this CL we will always attach a stencil buffer for rendering
that matches the stencil sample count of the proxy. We will even
downgrade a stencil attachment to one with less samples if necessary.
(In the past we would only guarantee that the attached stencil buffer
had a sample count >= to that of the proxy.)
