Wasm support

[Kantis]

I think adding wasm support makes sense once Kotlin 2.0 is out with better support for it, and once Kotest starts supporting testing for wasm targets.

kotest/kotest#3805

I have several multiplatform libraries that use kotest assertions. Kotest assertions is one of the remaining blockers for me to support wasm. There are a few others but it would be nice to get this out of the way sooner rather than later given that there is a pull request now.
