Look into Vulkan shader compilers

[VarLad]

Mesa's ZINK can output appropriate Vulkan SPIR-V from OpenCL (when using the bda backend)
These Vulkan shaders can be compiled to MSL, WGSL and HLSL by tools like SPIRV-Cross and Naga
It would be interesting to see if we can extend OpenCL.jl's compatibility even further using these tools.

Related to and depends on: #330 #311

What would that buy us over Rusticl+Zink? Without Rusticl, we'd need to use Vulkan APIs (or Metal APIs in your hypothetical Vulkan shard -> MSL), which seems like a step back.

Ah, my intention for this was primarily finding a way for OpenCL kernels to run directly on the web (in the browser) through compiling the Vulkan SPIRV Rusticl+Zink produce to WGSL. Primary usecase being writing functions in a Pluto that survive export to static HTML, for greater portability of Pluto notebooks.
Probably doesn't make sense as an OpenCL issue but web support does make sense for JuliaGPU as a whole in my opinion :)

Yeah, let's maybe move this to a discussion then.
