Dave Bartolomeo fa40d59332 Move older change notes to old-change-notes
Now that change notes are per-package, new change notes should be created in the `change-notes` folder under the affected pack (e.g., `cpp/ql/src/change-notes` for C++ query change notes. I've moved all of the change note files that were added before we started publishing them in packs to an `old-change-notes` directory under each language, to reduce the temptation to add new change notes there.

I'm working on a document to describe how and when to create change notes for packs separately.

* Improved modeling of the `PyYAML` PyPI package (imported as `yaml`) now includes `safe_load`, `unsafe_load`, and `full_load` (as well as the `..._load_all` functions). In the current version of PyYAML (5.4.1), only `safe_load` and `safe_load_all` are known to be safe from code execution exploits. Consequently, calls to the other functions are modeled as sinks of the _Deserializing untrusted input_ (`py/unsafe-deserialization`) query.
