squash-merge smart_holder branch into master (#5542)
* Pure `git merge --squash smart_holder` (no manual interventions).

* Remove ubench/ directory.

* Remove include/pybind11/smart_holder.h

* [ci skip] smart_ptrs.rst updates [WIP/unfinished]

* [ci skip] smart_ptrs.rst updates continued; also updating classes.rst, advanced/classes.rst

* Remove README_smart_holder.rst

* Restore original README.rst from master

* [ci skip] Minimal change to README.rst, to leave a hint that this is pybind11v3

* [ci skip] Work in ChatGPT suggestions.

* Change macro name to PYBIND11_RUN_TESTING_WITH_SMART_HOLDER_AS_DEFAULT_BUT_NEVER_USE_IN_PRODUCTION_PLEASE

* Add a note pointing to the holder reinterpret_cast.

* Incorporate suggestion by @virtuald: https://github.com/pybind/pybind11/pull/5542#discussion_r1967000989

* Systematically change most py::class_ to py::classh under docs/

* Remove references to README_smart_holder.rst

This should have been part of commit eb550d03d3.

* [ci skip] Fix minor oversight (``class_`` -> ``py::class_``) noticed by chance.

* [ci skip] Resolve suggestion by @virtuald

https://github.com/pybind/pybind11/pull/5542#discussion_r1969940605

* [ci skip] Apply suggestions by @timohl (thanks!)

* https://github.com/pybind/pybind11/pull/5542#discussion_r1970714551
* https://github.com/pybind/pybind11/pull/5542#discussion_r1971315329
* https://github.com/pybind/pybind11/pull/5542#discussion_r1971322821

* Replace `classh : class_` inhertance with `using`, as suggested by @henryiii

https://github.com/pybind/pybind11/pull/5542#issuecomment-2689034104

* Revert "Systematically change most py::class_ to py::classh under docs/"

This reverts commit ac9d31e13f.

* docs: focus on py::smart_holder instead of py::classh

Signed-off-by: Henry Schreiner <henryschreineriii@gmail.com>

* Restore minor general fixes that got lost when ac9d31e13f was reverted.

* Remove `- smart_holder` from list of branches in all .github/workflows

* Extend classh note to explain whitespace noise motivation.

* Suggest `py::smart_holder` for "most situations for safety"

* Add back PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT

This define was
* introduced with https://github.com/pybind/pybind11/pull/5286
* removed with https://github.com/pybind/pybind11/pull/5531

It is has been in use here:
* f02a2b7653/pybind11_protobuf/native_proto_caster.h (L89-L101)

Currently pybind11 unit tests for the two holder caster backwards compatibility traits

* `copyable_holder_caster_shared_ptr_with_smart_holder_support_enabled`
* `move_only_holder_caster_unique_ptr_with_smart_holder_support_enabled`

are missing.

* Add py::trampoline_self_life_support to all trampoline examples under docs/.

Address suggestion by @timohl:

* https://github.com/pybind/pybind11/pull/5542#issuecomment-2686452062

Add to the "please think twice" note: the overhead for safety is likely in the noise.

Also fix a two-fold inconsistency introduced by revert-commit 1e646c91b4:

1.

py::trampoline_self_life_support is mentioned in a note, but is missing in the example right before.

2.

The section starting with

    To enable safely passing a ``std::unique_ptr`` to a trampoline object between

is obsolete.

* Fix whitespace accident (indentation) introduced with 1e646c91b4

Apparently the mis-indentation was introduced when resolving merge conflicts for what became 1e646c91b4

* WHITESPACE CHANGES ONLY in README.rst (list of people that made significant contributions)

* Add Ethan Steinberg to list of people that made significant contributions (for completeness, unrelated to smart_holder work).

* [ci skip] Add to list of people that made significant contributions: major and/or influential contributors to smart_holder branch
