* Transfer bug fixes from #4888 wholesale. Full test coverage for all fixes is still missing.

* Add cmake option(PYBIND11_DISABLE_HANDLE_TYPE_NAME_DEFAULT_IMPLEMENTATION) and use in some tests.

* API: Make `numpy.h` compatible with both NumPy 1.x and 2.x

* TST: Update numpy dtype flags test to not covert flags to char

* API: Add `numpy2.h` instead and make `numpy.h` safe

This means that users of `numpy.h` cannot be broken, but need to
update to `numpy2.h` if they want to compile for NumPy 2.

Using Macros simply and didn't bother to try to remove unnecessary
code paths.

* API: Rather than `numpy2.h` use a define for the user.

* Thread `PYBIND11_NUMPY2_SUPPORT` through things and try to adept test matrix

* Small fixups (shouldn't matter)?

* Fixup.  Does upgrading scipy help?  (it shouldn't?)

(Some other small fixup)

* Use NumPy 2 nightlies for ubuntu-latest job also

* BUG: Fix numpy.bool check

* TST: Fix complexwarning

* BUG: Fix the fact that only the 50 slot is filled with the copy alias

(There were 3 functions all doing the same, only this slot survived 2.x)

* TST: One more test tweak

* TST: Use "long" name for long, since it changed on windows

* TST: Apparently we didn't always have ulong, so just use `L`

* TST: Enforce dtype='l' for test as default isn't long anymore on windows

* Rename macro and invert logic to PYBIND11_NUMPY_1_ONLY

* PYBIND11_INTERNAL_NUMPY_1_ONLY_DETECTED

* Test and code comment expansion

* CI: Use pre-releases of numpy/scipy from pip via explicit version

* CI: NumPy 2 only available on almalinux (as it is Python >=3.9)

* MAINT: Match name more exactly and adopt error phrasing

* MAINT: Pushed early, move helper to be private member

* fix error message compilation when using NumPy 1.x-only backcompat

* silence name shadowing warning

* chore: minor optimization

* doc: add litgen to the automatic generators list (compiling.rst)

Added this:

[litgen]_ is an automatic python bindings generator with a focus on generating
documented and discoverable bindings: bindings will nicely reproduce the documentation
found in headers. It is is based on srcML (srcml.org), a highly scalable, multi-language
parsing tool with a developer centric approach. The API that you want to expose to python
must be C++14 compatible (but your implementation can use more modern constructs).
