* Store `std::function<void (void *)>` del_fun; in `guarded_delete`
* Specialize the simple common case.
Using a `union` is complicated: https://en.cppreference.com/w/cpp/language/union
> If members of a union are classes with user-defined constructors and destructors, to switch the active member, explicit destructor and placement new are generally needed:
Using `std::variant` increases compile-time overhead.
It is currently unclear how much these effects matter in practice: optimization left for later.
* Add one test case (more later).
* Add `const` to resolve clang-tidy error.

This reverts commit fe59369f40.
According to https://docs.python.org/3.13/whatsnew/3.13.html:
Add PyThreadState_GetUnchecked() function: similar to
PyThreadState_Get(), but don't kill the process with a fatal error if
it is NULL. The caller is responsible to check if the result is
NULL. Previously, the function was private and known as
_PyThreadState_UncheckedGet().
* Workaround NVCC parse failure in `cast_op`
There is a bug in some CUDA versions (observed in CUDA 12.1 and 11.7 w/ GCC 12.2),
that makes `cast_op` fail to compile:
`cast.h:45:120: error: expected template-name before ‘<’ token`
Defining the nested type as an alias and using it allows this to work
without any change in semantics.

* Update pytest (which removes their dependency on py)
The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.
The particular codepath in question is the regular expression at py._path.svnurl.InfoSvnCommand.lspattern and is only relevant when dealing with subversion (svn) projects. Notably the codepath is not used in the popular pytest project. The developers of the pytest package have released version 7.2.0 which removes their dependency on py. Users of pytest seeing alerts relating to this advisory may update to version 7.2.0 of pytest to resolve this issue. See https://github.com/pytest-dev/py/issues/287#issuecomment-1290407715 for additional context.
* Added conditions so that we keep using 7.0.0 on python 3.6
* LazyInitializeAtLeastOnceDestroyNever v1
* Go back to using `union` as originally suggested by jbms@. The trick (also suggested by jbms@) is to add empty ctor + dtor.

* Add comment regarding `KeyboardInterrupt` behavior, based heavily on information provided by @jbms.
* Add `assert(PyGILState_Check())` in `gil_scoped_release` ctor (simple & non-simple implementation) as suggested by @EthanSteinberg.

* cmake: split extension
Into suffix and debug postfix. Pybind11 is currently treating both as
suffix, which is problematic when something else defines the
DEBUG_POSTFIX because they will be concatenated.
pybind11_extension sets SUFFIX to _d.something and if DEBUG_POSTFIX is
set to _d.
_d + _d.something = _d_d.something
The issue has been reported at:
