gh-127750: Restore inspect and pydoc support of singledispatchmethod (GH-130309)
The code is still flawed, because it does not recognize class and static
methods, and the first argument is not removed from the signature of
bound methods, but at least it does not worse than in 3.13 and older.

gh-127750: Fix and optimize functools.singledispatchmethod() (GH-130008)
Remove broken singledispatchmethod caching introduced in gh-85160.
Achieve the same performance using different optimization.

* Add more tests.

* Fix issues with __module__ and __doc__ descriptors.

gh-121676: Raise a ``DeprecationWarning`` if the Python implementation of ``functools.reduce`` is called with `function` or `sequence` as a keyword args (#121677)
Python implementation of `functools` allows calling `reduce`
with `function` or `sequence` as keyword args. This doesn't
match behavior of our C accelerator and our documentation
for `functools.reduce` states that `function`and `sequence`
are positional-only arguments.

Now calling a Python implementation of `functools.reduce`
with `function` or `sequence` as keyword args would raise
a `DeprecationWarning` and is planned to be prohibited in
Python 3.16.

functools: Give up on lazy-importing types (#124736)
PR #121089 added an eager import for types.MethodType, but
still left the existing hacks for lazily importing from types.

We could also create MethodType internally in functools.py (e.g.,
by using `type(Placeholder.__repr__)`, but it feels not worth it at
this point, so instead I unlazified all the usages of types in the
module.

bpo-38364: unwrap partialmethods just like we unwrap partials (#16600)
* bpo-38364: unwrap partialmethods just like we unwrap partials

The inspect.isgeneratorfunction, inspect.iscoroutinefunction and inspect.isasyncgenfunction already unwrap functools.partial objects, this patch adds support for partialmethod objects as well.

Also: Rename _partialmethod to __partialmethod__.
Since we're checking this attribute on arbitrary function-like objects,
we should use the namespace reserved for core Python.

The registry() method of functools.singledispatch() functions checks now
the first argument or the first parameter annotation and raises a TypeError if it is
not supported. Previously unsupported "types" were ignored (e.g. typing.List[int])
or caused an error at calling time (e.g. list[int]).
