Background: #2999, #4105, #4283, #4284
In a nutshell:
* Only macOS actually needs `PYBIND11_EXPORT_EXCEPTION` (#4284).
* Evidently (#4283), under macOS `PYBIND11_EXPORT_EXCEPTION` does not run the risk of introducing ODR violations,
* but evidently (#4283) under Linux it does, in the presumably rare/unusual situation that `RTLD_GLOBAL` is used.
* Windows does no have the equivalent of `RTLD_GLOBAL`, therefore `PYBIND11_EXPORT_EXCEPTION` has no practical benefit, on the contrary, noisy warning suppression pragmas are needed, therefore it is best left empty.
* Add option to force the use of the PYPY GIL scoped acquire/release logic to support nested gil access, see https://github.com/pybind/pybind11/issues/1276 and https://github.com/pytorch/pytorch/issues/83101
* Apply suggestions from code review
* Update CMakeLists.txt
* docs: update upgrade guide
* Update docs/upgrade.rst
* All bells & whistles.
* Add Reminder to common.h, so that we will not forget to purge `!WITH_THREAD` branches when dropping Python 3.6
* New sentence instead of semicolon.
* Temporarily pull in snapshot of PR #4246
* Add `test_release_acquire`
* Add more unit tests for nested gil locking
* Add test_report_builtins_internals_keys
* Very minor enhancement: sort list only after filtering.
* Revert change in docs/upgrade.rst
* Add test_multi_acquire_release_cross_module, while also forcing unique PYBIND11_INTERNALS_VERSION for cross_module_gil_utils.cpp
* Hopefully fix apparently new ICC error.

* clang-tidy fixes
* Workaround for PYPY WIN exitcode None
* Revert "Temporarily pull in snapshot of PR #4246"
This reverts commit 23ac16e859150f27fda25ca865cabcb4444e0770.
* Another workaround for PYPY WIN exitcode None
* Clean up how the tests are run "run in process" Part 1: uniformity
* Clean up how the tests are run "run in process" Part 2: use `@pytest.mark.parametrize` and clean up the naming.
* Skip some tests `#if defined(THREAD_SANITIZER)` (tested with TSAN using the Google-internal toolchain).
* Run all tests again but ignore ThreadSanitizer exitcode 66 (this is less likely to mask unrelated ThreadSanitizer issues in the future).
* bug fix: missing common.h include before using `PYBIND11_SIMPLE_GIL_MANAGEMENT`
For the tests in the github CI this does not matter, because
`PYBIND11_SIMPLE_GIL_MANAGEMENT` is always defined from the command line,
but when monkey-patching common.h locally, it matters.
* if process.exitcode is None: assert t_delta > 9.9
* More sophisiticated `_run_in_process()` implementation, clearly reporting `DEADLOCK`, additionally exercised via added `intentional_deadlock()`
* Wrap m.intentional_deadlock in a Python function, for `ForkingPickler` compatibility.
```
> ForkingPickler(file, protocol).dump(obj)
E TypeError: cannot pickle 'PyCapsule' object
```
Observed with all Windows builds including mingw but not PyPy, and macos-latest with Python 3.9, 3.10, 3.11 but not 3.6.
* Add link to potential solution for WOULD-BE-NICE-TO-HAVE feature.
* Add `SKIP_IF_DEADLOCK = True` option, to not pollute the CI results with expected `DEADLOCK` failures while we figure out what to do about them.
* Add COPY-PASTE-THIS: gdb ... command (to be used for debugging the detected deadlock)
* style: pre-commit fixes
* Do better than automatic pre-commit fixes.
* Add `PYBIND11_SIMPLE_GIL_MANAGEMENT` to `pytest_report_header()` (so that we can easily know when harvesting deadlock information from the CI logs).
