How to use custom WASM runtime?

[yjhmelody]

It seems to be using node's wasm runtime. But I need to run other wasm runtime for tests

Yes currently this project externalizes a lot of the runtime logic in JS. There have been plans in the past to make test binaries compatible with Wasi/minimize the required imports needed to executed and report tests.

I think that using WASI is probably moot, and a new specialized tool that generates tests with wasi should be created.

@willemneal I believe that we should refactor the strict equals transform, comparison functions, and expect() into their own library for this purpose.
