Java dependency search based on precise code intel

Created by: malomarrec

Java dependency search based on POM files will not work for Gradle (or setups that don't produce POM.xml files). We can use SCIP to produce a dependency graph.

• extend SCIP indexer to run full dependency resolution
• extend index format to include non-reference and transitive dependencies
• update code intel data ingestion to handle
• extend database model to allow for transitive dependencies tree
• extend backend to allow for dependency querying
