Add type_caster<PyObject> (#4601)
* Add `type_caster<PyObject>` (tests are still incomplete).

* Fix oversight (`const PyObject *`).

* Ensure `type_caster<PyObject>` only works for `PyObject *`

* Move `is_same_ignoring_cvref` into `detail` namespace.

* Add test_cast_nullptr

* Change is_same_ignoring_cvref from variable template to using.

```
test_type_caster_pyobject_ptr.cpp:8:23: error: variable templates only available with ‘-std=c++14’ or ‘-std=gnu++14’ [-Werror]
    8 | static constexpr bool is_same_ignoring_cvref = std::is_same<detail::remove_cvref_t<T>, U>::value;
      |                       ^~~~~~~~~~~~~~~~~~~~~~
```

* Remove `return_value_policy::reference_internal` `keep_alive` feature (because of doubts about it actually being useful).

* Add missing test, fix bug (missing `throw error_already_set();`), various cosmetic changes.

* Move `type_caster<PyObject>` from test to new include (pybind11/type_caster_pyobject_ptr.h)

* Add new header file to CMakeLists.txt and tests/extra_python_package/test_files.py

* Backport changes from https://github.com/google/pywrapcc/pull/30021 to https://github.com/pybind/pybind11/pull/4601

* Fix oversight in test (to resolve a valgrind leak detection error) and add a related comment in cast.h.

No production code changes.

Make tests more sensitive by using `ValueHolder` instead of empty tuples and dicts.

Manual leak checks with `while True:` & top command repeated for all tests.

* Add tests for interop with stl.h `list_caster`

(No production code changes.)

* Bug fix in test. Minor comment enhancements.

* Change `type_caster<PyObject>::name` to `object`, as suggested by @Skylion007

* Expand comment for the new `T cast(const handle &handle)` [`T` = `PyObject *`]

* Add `T cast(object &&obj)` overload as suggested by @Skylion007

The original suggestion leads to `error: call to 'cast' is ambiguous` (full error message below), therefore SFINAE guarding is needed.
