add RenderDocCapture to D3D12 quad, sphere, triangle integration tests

- Add RenderDocCapture include
- Initialize RenderDocCapture before D3D12 device creation
- SetDevice after D3D12 device initialization
- TriggerCapture on frame 29 before Present
- Add RenderDocCapture::Get().Shutdown() on exit
