Filter language worker console logs to just known workers

Recommendation from @pragnagopa in [this discussion](https://github.com/Azure/azure-functions-host/pull/8101#discussion_r794603982)

> I recommend scoping the change to language workers that the team owns - as of now they are shipped and packaged with the host - to avoid logging info level logs from language workers not owned by the team.

Basically, we need to:
1. Create a list of "well known" language workers owned by the Functions team
2. Use "debug" log level for console logs from any _other_ worker to ensure they don't clutter the logs
