Add support for parsing OSGi dependencies and .bnd files

[pantha704]

Resolves #3295.

This PR adds support for parsing OSGi bundle metadata and dependencies from MANIFEST.MF and .bnd properties files.

• Extends the existing jar_manifest.py to parse Import-Package and Require-Bundle headers, properly extracting version data, optional resolution parameters, and runtime scope, and outputting them as DependentPackage objects.
• Extracts other OSGi fields (like Export-Package, Bundle-Description, Require-Capability, etc.) into the extra_data mapping.
• Implements OsgiBndHandler within maven.py to handle *.bnd properties files natively using the javaproperties library.
• Includes comprehensive tests and regenerated data-driven test fixtures to validate OSGi parsing logic and expected payloads.
