Handing functionality off to jimple2cpg that includes many bug fixes

[DavidBakerEffendi]

Added

• Object data flow tests that explores fields and inter-procedural calls (both static + virtual).
• Data flow tests followed from JavaSrc2Cpg, specifically OperatorTests

Changed

• Importing jimple2cpg instead of duplicating work here.
• Removed parsing Jimple IdentityStmt since they end up duplicating parameters as locals.
• Swapped out the deprecated ParallelCpgPass for ConcurrentWriterCpgPass

Fixed

• Virtual calls now get passed the correct this object as the object the method is actually invoked with.
• Virtual call code properties now include the object invoking the method.
• Instance where Local nodes were duplicated for each time they were referenced
• Issue where NewCall(Operators.assignment) did not have methodFullName = Operators.assignment and thus messing up data flow paths

Related issues:
