rhi: d3d: Handle the case of passing in a texture array as depthTexture

Browse Source 
Behave identically to Vulkan, i.e. create a view that spans all array
elements. (except when the range is set)

This becomes relevant with multiview, where the depth/stencil attachment
the render target must be set up with a texture array as well, similarly
to the color attachment. But applies even to D3D11, even though it is
not common to use a texture array there, but it's possible.

Task-number: QTBUG-114896
Pick-to: 6.6
