I've identified some issues with our current approach to generate semanticdb data in a Scala 2.13 module:
When we stop scalac after phase semanticdb-typer, zinc is not able to incrementally compile the next round, therefore we effectively always generate all semanticdb files in each run
If we don't stop scalac after phase semanticdb-typer, we can generate semanticdb data incrementally, but we also unnecessarily compile all scala files to class files
Incremental compilation doesn't seem to clean semanticdb files for removed sources. So, we need to manually remove those that belong to non-existing source files
