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.

bpo-43137: webbrowser: Replace gvfs-open and gnome-open with "gio open" (GH-29154)
* [bpo-43137](): webbrowser: Prefer gio open over gvfs-open
    
    gvfs-open(1) was superseded by gio(1) in 2015, and removed from GNOME
    releases in 2018. Debian and its derivatives like Ubuntu currently still
    have a compatibility shim for gvfs-open, but we plan to remove it.
    
    webbrowser prefers xdg-settings and xdg-open over gvfs-open, so this
    will only have any practical effect on systems where the xdg-utils
    package is not installed.
    
    Note that we don't check for GNOME_DESKTOP_SESSION_ID before using gio.
    gio does the right thing on any desktop environment that follows
    freedesktop.org specifications, similar to xdg-settings, so it's
    unnecessary to guard in this way. GNOME_DESKTOP_SESSION_ID was deprecated
    in 2008 and removed from upstream gnome-session in 2018 (it's still
    present in Debian/Ubuntu for backward compatibility, but probably
    shouldn't be). The replacement way to detect a desktop environment is
    the XDG_CURRENT_DESKTOP environment variable, which is a colon-separated
    sequence where the first item is the current desktop environment and the
    second and subsequent items (if present) are other desktop environments
    that it resembles or is based on.
    
    Resolves: 

* [bpo-43137](): webbrowser: Never invoke gnome-open
    
    gnome-open was part of GNOME 2, which was superseded in around 2010 and
    is unmaintained. The replacement was gvfs-open, which was subsequently
    replaced by gio(1) (as used in the previous commit).

* [bpo-43137](): webbrowser: Don't run gvfs-open on GNOME
    
    gvfs-open was deprecated in 2015 and removed in 2018. The replacement
    is gio(1) (as used in a previous commit).
    
    GNOME_DESKTOP_SESSION_ID was deprecated in 2008 and removed in 2018.
    The replacement is XDG_CURRENT_DESKTOP (as mentioned in a previous
    commit).

---

To test this on a typical modern Linux system, it is necessary to disable the `xdg-settings` and `xdg-open` code paths, for example with this hack:

I haven't attempted to assess which of the specific web browsers such as Galeon are still extant, and which ones disappeared years ago. They could almost certainly be cleaned up, but that's beyond the scope of this PR.

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.

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.
