* First draft a subinterpreter embedding API
* Move subinterpreter tests to their own file
* Migrate subinterpreter tests to use the new embedded class.
* Add a test for moving subinterpreters across threads for destruction
And find a better way to make that work.
* Code organization
* Add a test which shows demostrates how gil_scoped interacts with sub-interpreters
* Add documentation for embeded sub-interpreters
* Some additional docs work
* Add some convenience accessors
* Add some docs cross references
* Sync some things that were split out into #5665
* Update subinterpreter docs example to not use the CPython api
* Fix pip test
* style: pre-commit fixes
* Fix MSVC warnings
I am surprised other compilers allowed this code with a deleted move ctor.
* Add some sub-headings to the docs
* Oops, make_unique is C++14 so remove it from the tests.
* I think this fixes the EndInterpreter issues on all versions.
It just has to be ifdef'd because it is slightly broken on 3.12, working well on 3.13, and kind of crashy on 3.14beta. These two verion ifdefs solve all the issues.
* Add a note about exceptions.
They contain Python object references and acquire the GIL, that means they are a danger with subinterpreters!
* style: pre-commit fixes
* Add try/catch to docs examples to match the tips
* Python 3.12 is very picky about this first PyThreadState
Try special casing the destruction on the same thread.
* style: pre-commit fixes
* Missed a rename in a ifdef block
* I think this test is causing problems in 3.12, so try ifdefing it to see if the problems go away.
* style: pre-commit fixes
* Document the 3.12 constraints with a warning
* Apply suggestions from code review

* Add a small section for py::bind_vector, py::bind_map & py::smart_holder
* Fix tiny oversight: Reference back to the current release v2.13 (not v2.12)
* Remove sentence: Using self._pybind11_conduit_v1_() ... should keep extension compatibility.
This isn't true, because we also modernized `PYBIND11_PLATFORM_ABI_ID`
(which I believe was absolutely necessary). I think it'll be too complicated
to explain that here, and there is a mention in the Upgrade guide.

* Oops, missed a warning pop
* Remove unused variable
* Update ci.yml
* Fix this embedded GIL test for free-threading
* Oops, need to use ptr() here
* This test created a subinterpreter when PYBIND11_SUBINTERPRETER_SUPPORT was off
So the fix is really this test should not be run in these older versions at all.
The hang was a GIL issue between the subinterpreters during pybind11::exception::what().
