Add dedicated subsection for `pathlib.owner()`, `group()`, `chmod()` and
`lchmod()`.

PyDict_Next no longer locks the dictionary in the free-threaded build. Locking
around individual PyDict_Next calls is not sufficient because the function
returns borrowed references and because it allows concurrent modifications
during the iteraiton loop.
The internal locking also interferes with correct external synchronization
because it may suspend outer critical sections created by the caller.
Add `pathlib.Path.copytree()` method, which recursively copies one
directory to another.
This differs from `shutil.copytree()` in the following respects:
1. Our method has a *follow_symlinks* argument, whereas shutil's has a
*symlinks* argument with an inverted meaning.
2. Our method lacks something like a *copy_function* argument. It always
uses `Path.copy()` to copy files.
3. Our method lacks something like a *ignore_dangling_symlinks* argument.
Instead, users can filter out danging symlinks with *ignore*, or
ignore exceptions with *on_error*
4. Our *ignore* argument is a callable that accepts a single path object,
whereas shutil's accepts a path and a list of child filenames.
5. We add an *on_error* argument, which is a callable that accepts
an `OSError` instance. (`Path.walk()` also accepts such a callable).

This makes the following macros public as part of the non-limited C-API for
locking a single object or two objects at once.
* `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()`
* `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()`
The supporting functions and structs used by the macros are also exposed for
cases where C macros are not available.
Add support for not following symlinks in `pathlib.Path.copy()`.
On Windows we add the `COPY_FILE_COPY_SYMLINK` flag is following symlinks is disabled. If the source is symlink to a directory, this call will fail with `ERROR_ACCESS_DENIED`. In this case we add `COPY_FILE_DIRECTORY` to the flags and retry. This can fail on old Windowses, which we note in the docs.
No news as `copy()` was only just added.
This exposes `PyUnstable_Object_ClearWeakRefsNoCallbacks` as an unstable
C-API function to provide a thread-safe mechanism for clearing weakrefs
without executing callbacks.
Some C-API extensions need to clear weakrefs without calling callbacks,
such as after running finalizers like we do in subtype_dealloc.
Previously they could use `_PyWeakref_ClearRef` on each weakref, but
that's not thread-safe in the free-threaded build.

The `inspect.ismethoddescriptor()` function did not check for the lack of
`__delete__()` and, consequently, erroneously returned True when applied
to *data* descriptors with only `__get__()` and `__delete__()` defined.

Add thread-safety clarifications to the SSLContext documentation. Per the issue:
This issue has also come up [here](https://github.com/psf/requests/pull/6667) where the matter was clarified by @tiran in [this comment](https://github.com/psf/requests/pull/6667):
> `SSLContext` is designed to be shared and used for multiple connections. It is thread safe as long as you don't reconfigure it once it is used by a connection. Adding new certs to the internal trust store is fine, but changing ciphers, verification settings, or mTLS certs can lead to surprising behavior. The problem is unrelated to threads and can even occur in a single-threaded program.
