internal/graphicsdriver/directx: specify DX level 12

Browse Source 
The DirectX initialization passed but crashed later on some old machines
supporting the feature level 11 but not 12.

This change fixes the issue by changing the required feature level from
11 to 12 so that the initialization fails and OpenGL is used as the
fallback.

Closes #2447
