Compile LightGBM to WebAssembly output

[ghost]

Summary

My team builds a c++ library which has direct dependency on LightGBM tool. We were planning to sandbox the tool and for that to complete we want documentation on how to compile LightGBM into WebAssembly code.

Motivation

Since sandboxing or running c++ code in browser is one of the hot topics in the market, LightGBM providing official documentation on compiling to WebAssembly will be a huge win for everyone.

Description

Requesting for new documentation to be created which shows compilation of LightGBM to WebAssembly. We don't have a preference for tool to be used for compilation as long as output is in wasm format.

Thanks very much for this @shyam-lab ! I've added it to our list of feature requests in #2302 . Per this repo's policy, I'll close this issue for now until someone leaves a comment saying they'd like to work on this.

But to set the right expectation...I don't believe this will be worked on by LightGBM's maintainers any time soon. I don't know if any of the current maintainers have any experience with WebAssembly, and we are already struggling to keep up with the demand for changes to the existing C, C++, Python, and R code in this project.

If you do figure out how to do this, please post your solution here.

If you or anyone else reading this are interested in doing the work to add this support and in maintaining that documentation, we can have a conversation here about possibly including that in this repository.
