D3D12: Always initialize depth stencil texture to 0 on Intel GPUs

This patch adds a toggle to force initializing depth stencil textures
to 0 on Intel D3D12 drivers as a driver issue will occur when we
create and copy into a depth stencil texture that is just created with
CreatePlacedResources() on Intel D3D12 drivers:
- For the depth stencil textures with RenderAttachment usage, they will
  always be cleared with ClearDepthStencilView() instead of copy, then
  the following copies will be correct.

In next patch we will handle the situation when the depth stencil
texture is not created with RenderAttachment usage.
