TCP connect in profiler wasm build

[tim37021]

Thanks for the great work you've created.

I would like to know if the support of tcp connection in wasm profiler planned? It will be really handy if Tracy is available on browser with tcp connecting, your browser demo work perfectly fine. Since Browser is a more stable environment.

Although tcp socket is not supported in browser, Emscripten can emulate it in help of WebSocket Proxy Server.
