gh-36802: Python toolchain as wheel packages

    
<!-- ^^^^^
Please provide a concise, informative and self-explanatory title.
Don't put issue numbers in there, do this in the PR body below.
For example, instead of "Fixes #1234" use "Introduce new method to
calculate 1+1"
-->
<!-- Describe your changes here in detail -->

We switch several pure Python packages that are part of
`PYTHON_TOOLCHAIN` from normal to wheel packages.

The only time that we carried a patch for any of these packages was in
2014–2016, a patch for pyparsing.

This reduces the complexity of our SPKGs, in line with previous PRs
#36267, #36429, #36129, #36794.
