d3d11: Drop legacy device support

Browse source 
Direct3D feature level 10 supported GPUs were released
more than 15 years ago, around the time when Windows
Vista / 7 were released. Also our d3d11 plugin/library
does not support feature level 9.x very well already.

* Known D3D_FEATURE_LEVEL_9_3 driver is
* "VirtualBox Graphics Adapter (WDDM)"
