KTOR-7675 Support CIO client for wasm-js and js (#4441)

* Support multiple client engines for JS/WasmJs
* CIO client Js/WasmJs support
* Enable CIO tests in client tests
* Make client engines `data object` to have `toString`
* Make ClientLoader work with multiple engines on js/wasmJs and so test CIO engine on nodejs(js+wasmJs)
