rhi: d3d11: fail early with a broken device
Broken meaning not being functional with shader model 5. This can happen with certain virtual machines where there is an accelerated DXGI adapter which then only supports a feature level lower than 11_0, and so SM 5.0 shaders do not work. Similarly, GPUs from 2009 and earlier may have a similar driver setup. We do not particularly care about such devices, however we should make sure it can be recognized early on (i.e. in create()) that something is not right and fail the entire QRhi initialization. Otherwise no error will occur until attempting to create the first shader via a QRhiGraphicsPipeline and that's way too late. This way clients such as Qt Quick can make an effort to retry with some other settings, most notably the PreferSoftwareRenderer flag, in order to pick the sw rasterizer based adapter (WARP).
