refactor: use UUID for Packages from pom.xml files.

[DmitriyLewen]

Description

There are cases when report contains Packages with same GAV (GroupID, ArtifactID, version).
But these are different packages (see #7824 (comment)).

To avoid confusing and build dependency graph correctly, we need to use UUID for each Package from pom.xml files.

This solution also fixes problem with relationships in SBOM formats for this case (see #7824 (comment))
