Subject: 8503 wgsl depth texture (#8645)

Add built-in type aliases for DepthTexture* and unify Sampler*Shadow

Add the following type aliases:
- DepthTexture1D, DepthTexture1DArray
- DepthTexture2D, DepthTexture2DArray
- DepthTexture2DMS, DepthTexture2DMSArray
- DepthTexture3D
- DepthTextureCube, DepthTextureCubeArray

These match with the type aliases for non-depth textures.

Also, unify the Sampler*Shadow type aliases with DepthTexture*
ones. This adds the following:

- Sampler2DMSShadow
- Sampler2DMSArrayShadow

and removes the Sampler3DArrayShadow type alias. As a side-effect, the
descriptions of Sampler*ArrayShadow type aliases are fixed
("texture-sampler for shadow" ==> "texture-sampler array for shadow").

Update the slang tests to use the newly introduced type aliases instead
of
the custom type aliases that use _Texture<> directly.

Add DepthTexture testing in
hlsl-intrinsic/texture/texture-intrinsics. Do this by extracting the
test logic of computeMain() in a separate function and parametrize it
for non-depth/depth texture types. This adds basic coverage for the
following types:

- DepthTexture1D
- DepthTexture2D
- DepthTexture3D
- DepthTextureCube
- DepthTexture1DArray
- DepthTexture2DArray
- DepthTextureCubeArray
