JK3D 492bba9242 Control channel: write each reply in one piece (#6389) (#6390) ...

* claim: #6389

* perf: write each control reply to the socket in one piece

The control server wrote each reply with writeln!(out, "{reply}") on the unbuffered TcpStream.
Formatting a serde_json::Value hands the writer every string, number and punctuation mark
separately, so each became its own write system call. A reply of a few megabytes (component.list
on a design with thousands of components) took about half a second to send.

Every reply is now serialized to one buffer and written at once. Writing one large Value to a
loopback TcpStream: 1.79 MB took 1,052 ms with writeln! and 4.9 ms with one write_all.

The test counts the write calls for a 2000-component reply (one) and reads it back.
