09a11f4166 Python: Update ImpliesDataflow test 
Turns out that now we can resolve the convoluted imports. Hurray!

6c3aabe1df Python: Support flow through import * 
Adds result for `ModuleVariableNode::getARead` corresponding to reads
that go through (chains of) `import *`.

This required a bit of a change to _which_ module variables we define.
Previously, we only included variables that were accessed elsewhere in
the same file, but now we must ensure to also include variables that may
be accessed through `import *`.

03b6ee3833 Python: Add import * test 
This test shows off a few things:

- transitive chains of `import *`
- multiple modules exporting the same name (to test for cross-talk)

651a76c9ce Python: Add CWE-532 to CleartextLogging 
Relevant for this query:

CWE-532: Insertion of Sensitive Information into Log File

> While logging all information may be helpful during development
> stages, it is important that logging levels be set appropriately
> before a product ships so that sensitive user data and system
> information are not accidentally exposed to potential attackers.

See https://cwe.mitre.org/data/definitions/532.html

JS also did this recently: https://github.com/github/codeql/pull/7103

e2652591a5 Python: Change perf fix PoorMansFunctionResolution 
Thanks @yoff, this leaves us with the following evaluation, which looks
very close to the one in the other fix (but with cleaner implementation)
-- both at 688k max tuples (although numbers are not exactly the same).

These are no longer correct, since the A1 category changed from 2017 to
2021, see https://owasp.org/Top10/#whats-changed-in-the-top-10-for-2021

Since only a very few queries had these tags, I think we're much better
off having them removed.
