Add support for GraalPy (#5380 )

* Initial support for GraalPy

* Mark tests that currently fail on GraalPy with xfail

* Add graalpy to CI

* Limit test deps on graalpy to available binary wheels

* Skip cmake test installed_function on GraalPy

CMake won't find libpython on GraalPy, it either fails or silently picks
CPython's libpython.

* Factor out setting function docstrings into a macro

* Try to narrow down skipped tests

Enable type-safe interoperability between different independent Python/C++ bindings systems. (#5296 )

* `self.__cpp_transporter__()` proof of concept: Enable passing C++ pointers across extensions even if the `PYBIND11_INTERNALS_VERSION`s do not match.

* Include cleanup (mainly to resolve PyPy build failures).

* Fix clang-tidy errors.

* Resolve `error: extra

* factor out platform_abi_id.h from internals.h (no functional changes)

* factor out internals_version.h from internals.h (no functional changes)

* Update CMakeLists.txt, tests/extra_python_package/test_files.py

* Revert "factor out internals_version.h from internals.h (no functional changes)"

This reverts commit 3ccea8cd43.

* Remove internals_version.h from CMakeLists.txt, tests/extra_python_package/test_files.py

* `.__cpp_transporter__()` implementation: compare `pybind11_platform_abi_id`, `cpp_typeid_name`

* Add PremiumTraveler

* Rename test_cpp_transporter_traveler_type.h -> test_cpp_transporter_traveler_types.h

* Expand tests: `PremiumTraveler`, `get_points()`

* Shuffle order of tests (no real changes).

* Move `__cpp_transporter__` lambda to `py::cpp_transporter()` regular function.

* Use `type_caster_generic::load(self)` instead of `cast<T *>(self)`

* Pass `const std::type_info *` via `py::capsule` (instead of `cpp_typeid_name`).

* Make platform_abi_id.h completely stand-alone.

* rename exo_planet.cpp -> exo_planet_pybind11.cpp

* Add exo_planet_c_api.cpp (incomplete).

* Fix silly oversight (wrong filename in `#include`).

* Resolve clang-tidy errors:

```

* Implement exo_planet_c_api GetLuggage(), GetPoints()

* Move new code from test_cpp_transporter_traveler_bindings.h to pybind11/detail/type_caster_base.h, under the name `class_dunder_cpp_transporter()`

* Fix oversight.

* Unconditionally add `__cpp_transporter__` method to all `py::class_` objects, but do not include that magic method in docstring signatures.

* Back out pybind11/detail/platform_abi_id.h for now. Maximizing reusability can be handled separately, later.

* Small cleanup.

* Restore and add to `test_call_cpp_transporter_*()`

* Ensure https://github.com/pybind/pybind11/issues/3788 does not bite again.

* `class_dunder_cpp_transporter()`: replace `obj.cast<std::string>()` with `std::string(obj)`

* Add (simple) copyright notices in all newly added files.

* Globally replace cpp_transporter with cpp_conduit

* style: pre-commit fixes

* IWYU fixes

* Rename `class_dunder_cpp_conduit()` -> `cpp_conduit_method()`

* Change `pybind11_platform_abi_id`, `pointer_kind` argument types from `str` to `bytes`.

This avoids the unicode decode/encode roundtrips:

* More robust (no decode/encode errors).

* Minor runtime optimization.

* Systematically rename `cap_cpp_type_info` -> `cpp_type_info_capsule` (no functional changes).

* Systematically replace `cpp_type_info_capsule` `name`: `"const std::type_info *"` -> `typeid(std::type_info).name()` (this IS a functional change).

This provides an extra layer of protection against C++ ABI mismatches:

* The first and most important layer is that the `PYBIND11_PLATFORM_ABI_ID`s must match between extensions.

* The second layer is that the `typeid(std::type_info).name()`s must match between extensions.

* Fix sort order accident in tests/CMakeLists.txt

* Apply suggestions from code review

* Add test_home_planet_wrap_very_lonely_traveler(), test_exo_planet_pybind11_wrap_very_lonely_traveler()
