Fix core-initiated D3D9/D3D11 driver switches

Browse Source 
Currently, RetroArch only does this for GL and Vulkan hardware render
contexts. Requesting a D3D11 context would result in the frontend
creating a GL context instead (or whatever was set in frontend config),
and then eventually crashing when it tried to render the UI.
