[WIP] feat: Add "deno jupyter" subcommand

[bartlomieju]

Closes #13016

TODO:

• Add support for DEBUG env variable
• Make stdio out less flaky (don't use channel for all messages)
• Investigate BrokenPipe errors we're getting and how we could improve that situation (Codec Error: Broken Pipe zeromq/zmq.rs#153)

Trying to do this all in a single file is becoming cumbersome. Can we create a cli/jupyter folder and start creating multiple files there?
