gh-137226: Fix get_type_hints() on generic TypedDict with stringified annotations (#138953)
This issue appears specifically for TypedDicts because the TypedDict constructor
code converts string annotations to ForwardRef objects, and those are not evaluated
properly by the get_type_hints() stack because of other shenanigans with type
parameters.
This issue does not affect normal generic classes because their annotations are not
pre-converted to ForwardRefs.
The fix attempts to restore the pre- #137227 behavior in the narrow scenario where
the issue manifests. It mostly makes changes only in the paths accessible from get_type_hints(),
ensuring that newer APIs (such as evaluate_forward_ref() and annotationlib) are not affected
by get_type_hints()'s past odd choices. This PR does not fix issue #138949, an older issue I
discovered while playing around with this one; we'll need a separate and perhaps more
invasive fix for that, but it should wait until after 3.14.0.

gh-137433: Fix deadlock with stop-the-world and daemon threads (gh-137735)
There was a deadlock originally seen by Memray when a daemon thread
enabled or disabled profiling while the interpreter was shutting down.
I think this could also happen with garbage collection, but I haven't
seen that in practice.
The daemon thread could be hung while trying acquire the global rwmutex
that prevents overlapping global and per-interpreter stop-the-world events.
Since it already held the main interpreter's stop-the-world lock, it
also deadlocked the main thread, which is trying to perform interpreter
finalization.
Swap the order of lock acquisition to prevent this deadlock.
Additionally, refactor `_PyParkingLot_Park` so that the global buckets
hashtable is left in a clean state if the thread is hung in
`PyEval_AcquireThread`.

The stack collector base class keeps all frames until export() is

aggregation logic to the subclass through the process_frames method.

GH-128520: pathlib ABCs: improve protocol for 'openable' objects (#134101)
Rename `pathlib._os.magic_open()` to `vfsopen()`. The new name is a bit
less abstract, and it aligns with the `vfspath()` method added in
5dbd27d .
Per discussion on discourse[^1], adjust `vfsopen()` so that the following
methods may be called:
- `__open_reader__()`
- `__open_writer__(mode)`
- `__open_updater__(mode)`
These three methods return readable, writable, and full duplex file objects
respectively. In the 'writer' method, *mode* is either 'a', 'w' or 'x'. In
the 'updater' method, *mode* is either 'r' or 'w'.
In the pathlib ABCs, replace `ReadablePath.__open_rb__()` with
`__open_reader__()`, and replace `WritablePath.__open_wb__()` with
`__open_writer__()`.
