This PR fixes a bug in the 3.9 branch where
``functools.singledispatchmethod`` did not properly wrap attributes such as
``__name__``, ``__doc__`` and ``__module__`` of the target method. It also
backports tests already merged into the 3.11 and 3.10 branches in #29328 and
#29390.

This commit fixes a bug in the 3.9 branch where stacking
`@functools.singledispatchmethod` on top of `@classmethod` or `@staticmethod`
caused an exception to be raised if the method was registered using
type-annotations rather than `@method.register(int)`. Tests for this scenario
were added to the 3.11 and 3.10 branches in #29034 and #29072; this commit
also backports those tests to the 3.9 branch.

The doctest module raised an error if a docstring contained an example that
attempted to access a classmethod property. (Stacking '@classmethod' on top of
`@property` has been supported since Python 3.9; see
https://docs.python.org/3/howto/descriptor.htmlGH-class-methods.)

An object implementing the os.PathLike protocol can represent a file
system path as a str or bytes object.
Therefore, _infer_return_type function should infer os.PathLike[str]
object as str type and os.PathLike[bytes] object as bytes type.

At import time, the xmlrpc.client module uses different date formats to
test strftime so it can format years with 4 digits consistently.
Depending on the underlying C library and its strftime implementation
some of these calls can result in ValueErrors, blocking the
xmlrpc.client module from being imported.
This commit changes the behavior of this bit of code to react to
ValueError exceptions, treating the format that caused them as an
non-viable option.

Make enter_context(foo()) / enter_async_context(foo()) equivalent to

Previously exceptions would be caught and re-raised with the wrong
context when explicitly overriding __context__ with None..

On Unix, if the sem_clockwait() function is available in the C
library (glibc 2.30 and newer), the threading.Lock.acquire() method
now uses the monotonic clock (time.CLOCK_MONOTONIC) for the timeout,
rather than using the system clock (time.CLOCK_REALTIME), to not be
affected by system clock changes.
configure now checks if the sem_clockwait() function is available.

unittest.TestCase.debug() raises now a SkipTest if the class or
the test method are decorated with the skipping decorator.
Previously it only raised a SkipTest if the test method was decorated
with other decorator in addition to the skipping decorator, or
if SkipTest was explicitly raised in the test or setup methods.
