[3.12] gh-71587: Drop local reference cache to `_strptime` module in `_datetime` (gh-120431)
The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation). That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters. This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).

In order to patch flask.g e.g. as in GH-84982, that
proxies getattr must not be invoked. For that,
mock must not try to read from the original
object. In some cases that is unavoidable, e.g.
when doing autospec. However, patch("flask.g",
new_callable=MagicMock) should be entirely safe.

[3.12] gh-120048: Make `test_imaplib` faster (GH-120050) (#120070)
The `test_imaplib` was taking 40+ minutes in the refleak build bots because
the tests waiting on a client `self._setup()` was creating a client that
prevented progress until its connection timed out, which scaled with the
global timeout.
We should set `connect=False` for the tests that don't want `_setup()` to
create a client.

times, so test_signal was taking >30 minutes.

[3.12] Improve documentation for typing.get_type_hints (GH-119928) (#119944)
- Explicit list of what it does that is different from
"just return __annotations__"
- Remove reference to PEP 563; adding the future import doesn't
do anything to type aliases, and in general it will never make
get_type_hints() less likely to fail.
- Remove example, as the Annotated docs already have a similar
example, and it's unbalanced to have one example about this
one edge case but not about other behaviors of the function.

The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated,

This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too,
and we should backport to 3.13 and 3.12 if possible.
