e76f02b016 Python: Minor refactor to use LocalSourceNode 
This just more correctly reflects the reality, since the type-tracking
predicate just below only holds for LocalSourceNode anyway.

b41a06a15c Python: Treat py/summary/lines-of-user-code as the primary summary metric 
Move the `lines-of-code` tag from `py/summary/lines-of-code`.
Code Scanning will eventually look for this tag.

The intent is to treat the number of lines of user code for Python as the summary of
how much code was analysed, ignoring both external libraries and generated code.
This matches the current baseline metric the CodeQL Action computes for Python.
We'll revisit this decision, and the baseline, if necessary.

eb1da152a0 Python: Rewrite ClickHouse SQL lib modeling 
This did turn into a few changes, that maybe could have been split into
separate PRs 🤷

* Rename `ClickHouseDriver` => `ClickhouseDriver`, to better follow
  import name in `.qll` name
* Rewrote modeling to use API graphs
* Split modeling of `aioch` into separate `.qll` file, which does re-use
  the `getExecuteMethodName` predicate. I feel that sharing code between
  the modeling like this was the best approach, and stuck the
  `INTERNAL: Do not use.` labels on both modules.
* I also added handling of keyword arguments (see change in .py files)

I _really_ wanted to call this `.await()`, but that did not fit in with
the convention, or the corresponding `getPromised` in JS.
