[GR-43385] Group by modules and JARs in code area breakdown.

[graalvmbot]

This PR extends the code area breakdown with module name and JAR file groups. This makes it easier for users to understand what part of their code base and external dependencies are contributing the most to the code area. It also reduces the number of possible entries because modules and JARs usually contain multiple packages.

For a Spring starter project, the result looks like this:
