DirectX12

-- Steps to reproduce the crash:
1. Clone the following project: https://github.cds.internal.unity3d.com/unity/Graphics-QA-FTP-GraphicsFormatTest/tree/master
2. Open the project with latest trunk
3. Switch to DirectX12 by going to Edit -> Project Settings... -> Player -> Other Settings -> Rendering -> Untick "Auto Graphics API for Windows" -> Drag & Drop "Direct3D12" to the top of the list -> Restart
4. Reimport all assets by going to Assets -> Reimport All -> Reimport
5. A driver timeout might occur & Unity crashes once the "Importing..." window is finished
