* Step 1: Establish new `PYBIND11_SMART_HOLDER_ENABLED` macro, but only under include/pybind11/
At the stage `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.
* Systematically replace all `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` with `PYBIND11_SMART_HOLDER_ENABLED` under tests/ and ubench/
As at the previous stage, `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.
* Introduce `PYBIND11_SMART_HOLDER_DISABLE` option.
* `#ifdef` out entire `wrap()` function to avoid `unused-parameter` warning-as-error under macos-13

The SMART_HOLDER_WIP comments are mostly from 2021. In the meantime, the
smart_holder code was extremely thoroughly tested in the Google codebase
(production code). Additionally, testing via PyCLIF-pybind11 provided
thousands of diverse use cases that needed to satisfy many million unit tests
(the success rate was about 99.999%).
* fix: use `__cpp_nontype_template_args` instead of gnu extensions
* fix: add feature test value
* fix: change `PYBIND11_TYPING_H_HAS_STRING_LITERAL` skip reason
* Replace `unique_ptr_cref_roundtrip()` with `pass_unique_ptr_cref()`, `rtrn_unique_ptr_cref()` to make the current behavior obvious.
* add in unique_ptr_storage, unique_ptr_storage_deleter
* Add shared_ptr_storage (with that disowning fails as expected).
* Add load_as_const_unique_ptr()
* Restore original struct_smart_holder.h
* factor out `smart_holder::extract_deleter()`
* Better error message.
* Misc cleanup/tidying.
* Use `re.match("ctor_arg(_MvCtor)*_MvCtor", ...)` for compatibility with MSVC, NVHPC, ICC
* Add small comments.
* Fix small, inconsequential oversight in test code.
* Apply suggestion by @iwanders under PR #5334
* Remove `std::move()` in `smart_holder::extract_deleter()`
* Add `static_assert()` following a suggestion by @iwanders under PR #5334
PREPARATION for:
PR #5332 — Fix handling of const unique_ptr<T, D> & (do not disown).
Splitting out so that the functional changes under PR #5332 will be more obvious.
The only functional change under this PR is that
```
assert(custom_deleter_ptr != nullptr);
```
is replaced with:
```
if (custom_deleter_ptr == nullptr) {
throw std::runtime_error(
std::string("smart_holder::extract_deleter() precondition failure (") + context
+ ").");
}

```
* Add back README_smart_holder.rst in tests/extra_python_package/test_files.py
* Restore smart_holder_poc.h as-is on smart_holder branch (i.e. undo `PYBIND11_SMART_HOLDER_PADDING`, which was meant for stress-testing only).
* Insert `std::move()` as suggested by @laramiel
* `property_cpp_function_sh_*` named specializations, as suggested by @laramiel (https://github.com/pybind/pybind11/pull/5257#discussion_r1688346807)
* Call `property_cpp_function_classic` member functions, rather than inlining the implementations.
* Use `PYBIND11_HAVE_INTERNALS_WITH_SMART_HOLDER_SUPPORT` in holder_comparison.cpp (holder_comparison.py is NOT changed accordingly in this commit, i.e. can still only be run if the smart_holder functionality is available).
* Systematically rename `loaded_as` to `load_as` (`shared_ptr`, `unique_ptr`) as suggested by @laramiel
* Make change as suggested by @laramiel. This makes it much more obvious that the latest implementation of `smart_holder_from_unique_ptr()` accepts all existing `return_value_policy` enum values except `copy`.
* Resolve `BAKEIN_WIP: Rewrite comment.` for `property_cpp_function_*` specializations.
* Resolve `BAKEIN_WIP: Add comment to explain: This is meant for stress-testing only.`
* Resolve all remaining BAKEIN_WIP (in pybind11/cast.h).
Leave only two pairs of SMART_HOLDER_BAKEIN_FOLLOW_ON comments: refactoring of copyable_holder_caster, move_only_holder_caster. This is best left until after the smart_holder branch is merged into the master branch.
* Remove obsolete `using holder_type = smart_holder;` in `load_helper`
* Add SMART_HOLDER_BAKEIN_FOLLOW_ON comment for `internals::default_holder`
* README_smart_holder.rst update (line count reduced from 356 to 123).
