llvm-core/llvm: enable py3.13 for old versions

Python is currently only used for two things in llvm:15, and that is:

- Test-time use of llvm-lit, see corresponding change to dev-python/lit
  for why it is safe to enable py3.13.

  Note that llvm-lit loads cfg files which are python scripts used by the
  test. Some unmaintained code removed in llvm:16 uses a python module
  removed in 3.13, but we never built it to begin with so the easiest
  fix is to remove it entirely so that llvm-lit does not try to load it
  and fail with ModuleNotFoundError.

- USE=docs. We could drop docs from ancient slots, but it is just
  sphinx with a trivial conf.py and it does work, so we might as well
  allow it.
