RFR: 8223077: Investigate module path support for dynamic CDS archive [v2]

[Calvin Cheung]

> Please review this patch for adding module path support for CDS dynamic archive.
> Before this patch, if a module path was specified when creating a base archive, the user
> won't be able to create a dynamic archive based on the base archive.
> VM will issue the following warning:
> "Dynamic archiving is disabled because base layer archive has module path"
> 
> This patch adds checking of the module patsh in the base archive and the ones specified
> for dynamic dumping. If the module paths are the same, dynamic archive will be created.
> 
> Testing: tiers 1, 2.
