Add WGSL support for slang-test (#5174)

* 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.

* 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.
