Give a warning when attempting to save a file that shadows a module
in the standard library.

• Issue: IDLE: warn if save-as name matches stdlib name #69708

1. The warning should only be emitted if the file extension matches Python source extensions. IDLE allows to edit other text files, they do not conflict with modules.
2. The warning should only be emitted for saving a new file. If file already exists, then the user already saved it and asked the question.
3. There should be more reliable way to determine if the name conflicts with an existing module. For example using importlib.util.find_spec().
