Implement a more robust IPC system between the launcher and client (#4159)

* Implement a more robust IPC system between the launcher and client

* Clippy fix and cargo fmt

* Switch to cached JsonReader with LENIENT parsing to avoid race conditions

* Make RPC send messages in lines

* Try to bind to either IPv4 or IPv6 and communicate version

* Move message handling into a separate function to avoid too much code in a macro
