Call _PyObject_DebugMallocStats() earlier in Py_FinalizeEx(), before
the interpreter is deleted.

Use directly memcpy() instead.

We make use of the same mechanism that we use for the static builtin types. This required a few tweaks.
The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately.
This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.

This makes the support official.

I was able to make use of the existing datetime_state struct, but there was one tricky thing I had to sort out. We mostly aren't converting to heap types, so we can't use things like PyType_GetModuleByDef() to look up the module state. The solution I came up with is somewhat novel, but I consider it straightforward. Also, it shouldn't have much impact on performance.
In summary, this main changes here are:
* I've added some macros to help hide how various objects relate to module state
* as a solution to the module state lookup problem, I've stored the last loaded module on the current interpreter's internal dict (actually a weakref)
* if the static type method is used after the module has been deleted, it is reloaded
* to avoid extra work when loading the module, we directly copy the objects (new refs only) from the old module state into the new state if the old module hasn't been deleted yet
* during module init we set various objects on the static types' __dict__s; to simplify things, we only do that the first time; once those static types have a separate __dict__ per interpreter, we'll do it every time
* we now clear the module state when the module is destroyed (before, we were leaking everything in _datetime_global_state)

The free-threaded build currently immortalizes objects that use deferred
reference counting (see gh-117783). This typically happens once the
first non-main thread is created, but the behavior can be suppressed for
tests, in subinterpreters, or during a compile() call.
This fixes a race condition involving the tracking of whether the
behavior is suppressed.

The `sem_clockwait` function is not currently instrumented, which leads
to false positives.

- 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 GIL may be disabled concurrently with this call so we need to use a
relaxed atomic load.

Remove the delegation of `int` to the `__trunc__` special method: `int` will now only delegate to `__int__` and `__index__` (in that order). `__trunc__` continues to exist, but its sole purpose is to support `math.trunc`.

PEP 667's description of the planned changes to PyEval_GetLocals
was internally inconsistent when accepted, so the docs added for
gh-74929 didn't match either the current behaviour or the intended
behaviour once gh-118934 is fixed.
This PR updates the documentation and 3.13 What's New to match the
intended behaviour (once gh-118934 is fixed).
It also tidies up lingering references to `f_locals` always being a
dictionary (this hasn't been true since at least when custom
namespace support for class statement execution was added)

Implement `shutil._rmtree_safe_fd()` using a list as a stack to avoid emitting recursion errors on deeply nested trees.
`shutil._rmtree_unsafe()` was fixed in a150679f90.

Only call `gc_restore_tid()` from stop-the-world contexts.
`worklist_pop()` can be called while other threads are running, so use a
relaxed atomic to modify `ob_tid`.
