hw_dxva2: create a IDirect3D9Ex device 

This should allow us to create the device in situations when
Direct3DCreate9 normally fails, for example if no user is logged in.
While the later use-case is not very interesting, I hope it to work in
some other situations as well, for example while certain drivers are in
exclusive full screen mode.

This is available since Windows 7, so I'm removing the old call
completely.
