WebAssembly support

[v1rtl]

Summary

Implement proper support for both WASM and WASI (first WASM).

The PR for WASM is here: #5084

Right now chunk retrieval is not working, which is either related to wasm interop or to a bug in the retrieval mechanism when there's just two nodes.

Notes

Viper supports WASM as of 1.7.1: spf13/viper#1071
go-libp2p fails to compile because of WebRTC transport: libp2p/go-libp2p#3277

Motivation

being able to run bee in a browser

Implementation

go flags

Drawbacks

idk
