Add an option to disable the logs in the dev tools console

[jtpio]

Problem

Currently there are quite a few messages in the dev tools console when starting a kernel:

These messages can add a bit of noise and some deployments might want to silent them.

Proposed Solution

• Provide an option to disable the logs
• Show the logs by default or not?

Additional context

Testing with:

• jupyterlite-xeus-python 0.9.0
• empack 3.0.0
