Commit Message

The __cached__ attribute has been deprecated since Python 3.13 and has
been removed in 3.15:

  The __cached__ attribute on modules, which was deprecated since
  version 3.13, is no longer set or taken into consideration by the
  import system or standard library. Use __spec__.cached instead.[1]

Replace __cached__ with __spec__.cached, and remove obsolete exception
handling that doesn't get triggered with the current standard library.
