bpo-45582: Port getpath[p].c to Python (GH-29041) 
The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code.

This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

that user-defined methods and methods inherited from mixin classes always
show up in the output of `help()`. This change also makes it easier for

bpo-45703: Invalidate _NamespacePath cache on importlib.invalidate_ca… (GH-29384) 
Consider the following directory structure:

    .
    └── PATH1
        └── namespace
            └── sub1
                └── __init__.py

And both PATH1 and PATH2 in sys path:

    $ PYTHONPATH=PATH1:PATH2 python3.11
    >>> import namespace
    >>> import namespace.sub1
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> ...

While this interpreter still runs, PATH2/namespace/sub2 is created:

    .
    ├── PATH1
    │   └── namespace
    │       └── sub1
    │           └── __init__.py
    └── PATH2
        └── namespace
            └── sub2
                └── __init__.py

The newly created module cannot be imported:

    >>> ...
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> import namespace.sub2
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ModuleNotFoundError: No module named 'namespace.sub2'

Calling importlib.invalidate_caches() now newly allows to import it:

    >>> import importlib
    >>> importlib.invalidate_caches()
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> import namespace.sub2
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace', '.../PATH2/namespace'])

This was not previously possible.

Eric V. Smith d3062f672c
bpo-44649: Fix dataclasses(slots=True) with a field with a default, but init=False (GH-29692) 
Special handling is needed, because for non-slots dataclasses the instance attributes are not set: reading from a field just references the class's attribute of the same name, which contains the default value. But this doesn't work for classes using __slots__: they don't read the class's attribute. So in that case (and that case only), initialize the instance attribute. Handle this for both normal defaults, and for fields using default_factory.
