[PATCH 1/8] d3d11/tests: Add more tests for ID3D11DeviceContext1_SwapDeviceContextState.

[Rémi Bernon]

Better checking multiple context swap side effects.

So it looks like that a device context state tracks a unique state per
device (or per context, but it only works on immediate contexts).

This requires anyway a new wined3d object to track the hidden refcount,
but then the corresponding states also have to be tracked on each
device, and doesn't seem to be viable to keep it on the d3d11 side.
