* 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.

* 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]} {}

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().
* 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.

* Update pytest (which removes their dependency on py)
The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.
The particular codepath in question is the regular expression at py._path.svnurl.InfoSvnCommand.lspattern and is only relevant when dealing with subversion (svn) projects. Notably the codepath is not used in the popular pytest project. The developers of the pytest package have released version 7.2.0 which removes their dependency on py. Users of pytest seeing alerts relating to this advisory may update to version 7.2.0 of pytest to resolve this issue. See https://github.com/pytest-dev/py/issues/287#issuecomment-1290407715 for additional context.

* cmake: split extension
Into suffix and debug postfix. Pybind11 is currently treating both as
suffix, which is problematic when something else defines the
DEBUG_POSTFIX because they will be concatenated.
pybind11_extension sets SUFFIX to _d.something and if DEBUG_POSTFIX is
set to _d.
_d + _d.something = _d_d.something
