c630e22c1c

Add `static_assert`s to enforce that `py::smart_holder` is combined with `py::trampoline_self_life_support` (#5633 )

* Strictly enforce: trampoline must inherit from trampoline_self_life_support when used in combination with smart_holder

* Simplify test_class_sh_trampoline_basic.cpp,py (only one Abase is needed now)

* Replace obsolete sophisticated `throw value_error()` with a simple `assert()`

* Strictly enforce: trampoline should inherit from trampoline_self_life_support only if used in combination with smart_holder

* Resolve clang-tidy error

```
/__w/pybind11/pybind11/tests/test_class_sh_trampoline_basic.cpp:35:46: error: the parameter 'obj' is copied for each invocation but only used as a const reference; consider making it a const reference [performance-unnecessary-value-param,-warnings-as-errors]
   35 | int AddInCppSharedPtr(std::shared_ptr<Abase> obj, int other_val) {
      |                                              ^
      |                       const                 &
```

* Disable new static_assert if PYBIND11_RUN_TESTING_WITH_SMART_HOLDER_AS_DEFAULT_BUT_NEVER_USE_IN_PRODUCTION_PLEASE is defined.

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

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

* 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 1e646c91b4cfd78228f7e3f6d2e0d649bad8b30a:

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
