7c68ef354b gst-python: Fix override loading in python >= 3.12
The `imp` module got removed in python 3.12 and the `importlib` module should be
used instead.

This is also a good excuse to switch to the new finder module from PEP 451 :
https://www.python.org/dev/peps/pep-0451/

This only requires implement the `find_spec()` method in our custom loaders

2be13c82aa gst-python: Fix API call for Python 3.13
_PyUnicode_AsString() is deprecated and PyUnicode_AsUTF8() should be used
instead. The new function was introduced in Python 3.3 and returns const
since Python 3.7, which is now required.

3683cd9052 gst-python: fix build and usage in Windows
Windows require the python module to be linked to GStreamer.

b87aaf4d28 python: More functions can be called before gst_init()
Configuration of our debugging system is possible before init, and in
fact is necessary too, otherwise the settings won't apply to logging
that happens during init.

For instance, since you cannot register a log function before you call
init in python, there is no way for you to log errors during init to
whatever logging service your app uses.

5f0493d33a meson: Set install_tag on some targets
Trying to follow recommendation from Meson documentation:
https://mesonbuild.com/Installing.html#installation-tags

Move tools into 'bin' or 'bin-devel' categories to keep only libs and
plugins in the default 'runtime' category. This simplifies distribution
of GStreamer application skipping parts that are not needed, similarly
to what Cerbero does by hardcoding huge list of files.

37366ff2f4 python: Do not call gst_init when it is already is_initialized
GStreamer plugins written in python need to call `Gst.init` to ensure
that GStreamer is initialized so when loading a python plugin, we might
be recursively calling `gst_init` which is not a good idea.

Meson tries to guess the tag (runtime, devel, etc) for every installed
file, but it cannot guess them all. There is a list at the end of
meson-log.txt of files we need to tag manually.

1babccfe50 python: Fix using overrides when not building PyGObject
Since 547570cd79 we do not always build
PyGObject and our development environment is broken when trying to use
GStreamer python when built against system PyGObject with the following
error importing Gst in there:

```
12345678** (gst-plugin-scanner:710617): CRITICAL **: 11:45:02.343: can't find gi.repository.Gst
Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/gi/repository/__init__.py", line 23, in <module>
    from ..importer import DynamicImporter

ImportError: cannot import name 'load_overrides' from 'gi.overrides' (/var/home/thiblahute/devel/gstreamer/gstreamer/subprojects/gst-editing-services/bindings/python/gi/overrides/__init__.py)
Factory Details:
```

The approach to fixing it is to implement override `gi` in
`gst-python/gi/` which we add to `PYTHONPATH`) and in there reset the
`gi` module to the right place and we get overrides from paths from
`_GI_OVERRIDES_PATH` we set in `gst-env.py` which points to all the
overrides that will be installed.
