feat(poly check, poly libs): include package distributions top namespace for known aliases

[DavidVujic]

Description

Collect the top namespace for the package distributions.

Example:
Adding a third-party library that adds features into a sub-namespace, such as "google-cloud-storage".

Importing it in Python: from google import cloud or from google.cloud import storage.

The added feature will locate the top-namespace - i.e. google - based on the details of the package distribution data.

Motivation and Context

This should make the poly check and poly libs more correct, when analyzing and reporting on third-party dependencies, and less need for the --alias option.

Solving issues discussed in #209

How Has This Been Tested?

✅ CI
✅ Unit test
✅ running the third-party libs lookup in the REPL
