Add support for Kotlin/Wasm

[sdeleuze]

I tried to use Dokka on a Kotlin/Wasm project like the ones in https://github.com/vmware-wasmstack/wasm-languages/tree/main/kotlin, when running ./gradlew dokkaHtml, it fails with a Unrecognized platform: wasm error.

Now that Kotlin 1.8 has been released, it would be great if Dokka adds support for this platform (I need it for a project).

Thanks for the report, didn't think we'd get wasm user projects so soon :)

We should get back to it after updating our compiler dependencies to Kotlin 1.8.0, it's still in progress.

This isn't a "good first issue" per se, but if you or @bashor or @skuzmich want to contribute this - let me know, I'll provide more details as to what needs to be done, how to build/test Dokka locally and so on
