* Use the assembly description as target when disassembling
I believe this is a bugfix.
It seems to have worked before because up until the WGSL case, the disassembler has been
the same executable as the one producing the binary to be disassembled.
* Add Tint as a downstream compiler
This closes issue #5104.
* Add downstream compiler for Tint.
* Tint is wrapped in a shared library, 'slang-tint' available from [1].
* The header file for slang-tint.dll is added in external/slang-tint-headers.
* Add some boilerplate for WGSL targets.
* Add an entry point test for WGSL.
[1] https://github.com/shader-slang/dawn/releases/tag/slang-tint-0
* Add WGSL_SPIRV as supported target for Glslang
* Add WebGPU support to slang-test
This helps to address issue #5051.
* Disable lots of crashing compute tests for 'wgpu'
This closes issue #5051.

* Implement texture_storage_Xd in WGSL
This commit implements `texture_storage_Xd` in WGSL, which is similar
to RWTextureXD in HLSL.
It is intresting that `texture_storage_Xd` doesn't take the shader
type as its input argument at all.
Instead, it takes "texel format" enum value as its first template
parameter, which can be found here:
https://www.w3.org/TR/WGSL/#storage-texel-formats
As an example, `texture_storage_2d<rg32uint, read_write>` expects
vec4<u32> as a value type for `Load` and `Store`, where Z-component
will be ignored and treated as zero and W-component will be treated
always as 1. The type `u32` is inferred from the enum value `rg32uint`.
Note that the number of component is always fixed to 4 regardless how
many components are actually stored.

* 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.

* Implement math intrinsics for WGSL
This commit implements math related intrinsics and a few others for
WGSL.
The implementation is based on the following doc,
https://www.w3.org/TR/WGSL
slang-test was looking for the downstream compiler for WGSL even though
it is not used.
This commit adds a minimal change to avoid the crash.
