* pybind11.pc: use pcfiledir for relative destinations
If the datarootdir is absolute, just use the absolute path directly.
However, if it is relative, we can compute the prefix from the location
of the `.pc` file itself. This allows the install to be relocatable.
* chore: use 3.20's cmake_path if available
* style: pre-commit fixes
* Update CMakeLists.txt

* Equivalent of 5718e4d080
* Resolve clang-tidy errors.
* Moving test_PPCCInit() first changes the behavior!
* Resolve new Clang dev C++11 errors:
```
The CXX compiler identification is Clang 17.0.0
```
```
pytypes.h:1615:23: error: identifier '_s' preceded by whitespace in a literal operator declaration is deprecated [-Werror,-Wdeprecated-literal-operator]

* Specifically exclude `__clang__`
* Snapshot of debugging code (does NOT pass pre-commit checks).
* Revert "Snapshot of debugging code (does NOT pass pre-commit checks)."
This reverts commit 1d4f9ff263.
* [ci skip] Order Dependence Demo
* Revert "[ci skip] Order Dependence Demo"
This reverts commit d37b5409d4.
* One way to deal with the order dependency issue. This is not the best way, more like a proof of concept.
* Move test_PC() first again.
* Add `all_type_info_add_base_most_derived_first()`, use in `all_type_info_populate()`
* Revert "One way to deal with the order dependency issue. This is not the best way, more like a proof of concept."
This reverts commit eb09c6c1b9.
* clang-tidy fixes (automatic)
* Add `is_redundant_value_and_holder()` and use to avoid forcing `__init__` overrides when they are not needed.
* Streamline implementation and avoid unsafe `reinterpret_cast<instance *>()` introduced with PR #2152
The `reinterpret_cast<instance *>(self)` is unsafe if `__new__` is mocked,
which was actually found in the wild: the mock returned `None` for `self`.
This was inconsequential because `inst` is currently cast straight back to
`PyObject *` to compute `all_type_info()`, which is empty if `self` is not
a pybind11 `instance`, and then `inst` is never dereferenced. However, the
unsafe detour through `instance *` is easily avoided and the updated
implementation is less prone to accidents while debugging or refactoring.
* Fix actual undefined behavior exposed by previous changes.
It turns out the previous commit message is incorrect, the `inst` pointer is actually dereferenced, in the `value_and_holder` ctor here:
f3e0602802/include/pybind11/detail/type_caster_base.h (L262-L263)
```
259 // Main constructor for a found value/holder:
260 value_and_holder(instance *i, const detail::type_info *type, size_t vpos, size_t index)
261 : inst{i}, index{index}, type{type},
262 vh{inst->simple_layout ? inst->simple_value_holder
263 : &inst->nonsimple.values_and_holders[vpos]} {}
```

* Resolve clang-tidy error:
```

```

According to https://docs.python.org/3.13/whatsnew/3.13.html:
Add PyThreadState_GetUnchecked() function: similar to
PyThreadState_Get(), but don't kill the process with a fatal error if
it is NULL. The caller is responsible to check if the result is
NULL. Previously, the function was private and known as
_PyThreadState_UncheckedGet().
Passing `py::exception<void>` does not compile:
```
pytypes.h:459:36: error: could not convert ‘{h, pybind11::object::borrowed_t()}’ from ‘<brace-enclosed initializer list>’ to ‘pybind11::exception<void>’
459 | return {h, object::borrowed_t{}};
```
* Workaround NVCC parse failure in `cast_op`
There is a bug in some CUDA versions (observed in CUDA 12.1 and 11.7 w/ GCC 12.2),
that makes `cast_op` fail to compile:
`cast.h:45:120: error: expected template-name before ‘<’ token`
Defining the nested type as an alias and using it allows this to work
without any change in semantics.
Fixes#4606
* style: pre-commit fixes
* Add comments to result_t referencing PR
