DX11: Disable MSAA when using a GPU which only supports D3D 10.0. 

10.0 level hardware can't create multisampled depth buffers which can be bound as shader resources as well, but we need that for e.g. EFB access or EFB copies.
Only multisampling the color buffer doesn't work either since color and depth targets must be using the same sample count.
