It "kinda" works now, but it really is not a pretty solution. Adding all these
"tracked" objects is SUPER annoying... it _would_ be possible to skip them, but
that seems like it will give the wrong edges for dataflow/taintflow queries :|
A good chunk of it should be able to be removed with access-paths like C# does
for library modeling. Some of it could be solved by better type-tracking API
like API Graphs... but it seems like we generally are just lacking the
nice-to-have features like `.getAMemberCall` and the like. See
https://github.com/github/codeql/pull/4082/files#diff-9aa94c4d713ef9d8da73918ff53db774L33
The import doesn't actually work the intended way, so running
```
$ python python/ql/test/experimental/library-tests/CallGraph/test.py
```
will procude no output. but our extractor will extract the things we need, so
for a quick fix this will need to suffice.
