[smart_holder] Bug fix: std::unique_ptr deleter needs to be copied. (#4850)
* Store `std::function<void (void *)>` del_fun; in `guarded_delete`
* Specialize the simple common case.
Using a `union` is complicated: https://en.cppreference.com/w/cpp/language/union
> If members of a union are classes with user-defined constructors and destructors, to switch the active member, explicit destructor and placement new are generally needed:
Using `std::variant` increases compile-time overhead.
It is currently unclear how much these effects matter in practice: optimization left for later.
* Add one test case (more later).
* Add `const` to resolve clang-tidy error.
```

* Introduce `struct custom_deleter` to ensure the deleter is moved as desired (the lambda function only captures a reference, which can become dangling).
* Resolve helpful clang-tidy errors.

* Workaround for gcc 4.8.5, clang 3.6
* Transfer reduced test here.
Reduced from a PyCLIF use case in the wild by @wangxf123456 (internal change cl/565476030).
* Add missing include (clangd Include Cleaner)
* Change `std::move` to `std::forward` as suggested by @iwanders.
* Add missing includes (clangd Include Cleaner)
* Use new `PYBIND11_TESTS_PURE_CPP_SMART_HOLDER_POC_TEST_CPP` to exclude `smart_holder::as_unique_ptr` method from production code.
* Systematically add `PYBIND11_TESTS_PURE_CPP_SMART_HOLDER_POC_TEST_CPP` to mark code that is not used from production code. Add comment to explain.
* Very simple experiment related to https://github.com/pybind/pybind11/pull/4850#issuecomment-1789780676
Does the `PYBIND11_TESTS_PURE_CPP_SMART_HOLDER_POC_TEST_CPP` define have anything to do with it?
* Revert "Very simple experiment related to https://github.com/pybind/pybind11/pull/4850#issuecomment-1789780676"
