feat(deps): identify circular brick dependencies

[DavidVujic]

Description

The poly tool now detects circular dependencies between bricks, to avoid any possible runtime errors.

The poly deps and poly deps --brick <the brick> now reports on bricks that are both used by and used in a brick.

The notification is information, the command will not return with a failed exit code. The reason is that circular brick dependencies can work without runtime errors.

Motivation and Context

Solves feature request #394

How Has This Been Tested?

✅ CI
✅ Unit tests
✅ Local run of the command on the polylith repo itself containing two circular brick dependencies (see #393)
