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

* WGSL texture support for depth and multisampled
This commit fixes a few issues with WGSL texture intrinsics.
- static_assert-s are corrected.
- Gather functions work properly with depth textures
- Load functions work properly with depth textures and multisampled
textures

This PR implements the texture gather functions for WGSL.
The pattern was very similar to how Metal was implemented.
Before copy and paste from the Metal implementation, I had to
clean up the Metal implementation to make it more readable
and maintainable.
Gather functions are available only for 2D and 3D textures.
Their `array` and `depth` variants may or may not be supported depending on the target.
`static_assert` ensures that Gather functions are available only for 2D and 3D textures.
Removed incorrect use of "$p" argument for targeting GLSL.

This commit implements all of the texture intrinsics for WGSL except "Gather" and sampler-less.
They will be implemented in a separate PR.
A few things to note:
- texture sampling functions are available only for the fragment shader stage; not for compute
- WGSL doesn't have any functions similar to CalculateLevelOfDetail or CalculateLevelOfDetailUnclamped.
- WGSL doesn't have a function overlaoding for textureSample with "clamp" or "status" arguments.
- WGSL doesn't support Load operation with offset for texture_multisampled_XX and texture_storage_XX.
- WGSL supports only four types of depth textures: 2D, 2D_array, cube and cube_array.
- WGSL doesn't support "offset" variants for cube and cube_array.
