I spent too much time trying to navigate validate Python code to figure
out where a test was coming from. Hoping that it's slightly easier for
the next person, this patch:
* Adds type annotations to setup_tests(), for the sake of code
navigation.
* Adds comments matching each test generator with the patterns of test
names it produces.
* Removes an if statement in `register_default_scenarios()` where both
branches have the same exact code with the same exact very long list.
* Removes NamedDic [sic] and replaces it with SimpleNamespace from the
standard library (3.3+) which has the same purpose and API.

There were a couple strings containing \(. That is not a valid escape
sequence in Python. The escape sequence was meant for GStreamer, and as
such either the backslash should be doubled or a raw string must be
used. This patch uses the latter for readability.
Python 3.13 will print a warning when a invalid escape sequence in a
string is found.
As a drive-by fix, this patch fixes fixes whitespace issues in the file
to make the Python linter happy.
