[3.10] bpo-45680: Clarify documentation on ``GenericAlias`` objects (GH-29335) (GH-30688)

The documentation on ``GenericAlias`` objects implies at multiple points that
only container classes can define ``__class_getitem__``. This is misleading.
This PR proposes a rewrite of the documentation to clarify that non-container
classes can define ``__class_getitem__``, and to clarify what it means when a
non-container class is parameterized.

See also: initial discussion of issues with this piece of documentation in
GH-29308, and previous BPO issue [42280]().

Also improved references in glossary and typing docs. Fixed some links.

This reverts commit ea251806b8dffff11b30d2182af1e589caf88acf.

Keep "assert(interned == NULL);" in _PyUnicode_Fini(), but only for
the main interpreter.

Keep _PyUnicode_ClearInterned() changes avoiding the creation of a
temporary Python list object.

Leave the PyInterpreterState structure unchanged to keep the ABI
backward compatibility with Python 3.10.0: rename the "interned"
member to "unused_interned".

bpo-40477: macOS Python Launcher app fixes for recent macOS releases (GH-30348) (GH-30349)

This change solves two problems encountered by users of the macOS Python Launcher app on recent macOS releases (10.14+):

- The launcher app was no longer able to launch the macOS Terminal.app to run a script.

- Even if Terminal.app was already launched, the launcher app was unable to send an Apple Event to Terminal.app to open and run Python with the desired .py file.
