Add JSON-RPC echo server for validation suite

Browse Source 
Replaces the external jrpces binary dependency with a self-contained
Python script. The server supports TCP (newline-delimited JSON, port 4321)
and UDP (port 4323), handles JSON-RPC 1.0 and 2.0, and implements:
  - echo(*args) -> [args, {}]
  - unknown methods -> error {code: -32000, message: "function not found"}

test.tum is updated to launch jrpc_echo_server.py via python3 and wait
for the "ready" readiness message before running tests.
