Move sampleAlphaToCoverage out of blendState

This is the second step towards exposing OES_draw_buffers_indexed (that defines independent blend state for each draw buffer). This flag is global in all graphics APIs, however D3D11 technically puts it in the blend state. D3D11: BlendStateKey was extended to keep existing D3D11 state caching semantics. D3D9: a comment was added explaining why this feature was never implemented there.
