[3.10] Document func parameter of locale.atof (GH-18183) (GH-32262)

The second parameter (named `func`) has been present since the `locale`
module was introduced in eef1d4e8b1, but has never been documented.

This commit updates the documentation for `locale.atof` to clarify the
behavior of the function and how the `func` parameter is used.

Replace the child process `typeperf.exe` with a daemon thread that reads the performance counters directly.  This prevents the issues that arise from inherited handles in grandchild processes (see issue37531 for discussion).

We only use the load tracker when running tests in multiprocess mode. This prevents inadvertent interactions with tests expecting a single threaded environment.  Displaying load is really only helpful for buildbots running in multiprocess mode anyway.

bpo-42369: Fix thread safety of zipfile._SharedFile.tell (GH-26974)

The `_SharedFile` tracks its own virtual position into the file as
`self._pos` and updates it after reading or seeking. `tell()` should
return this position instead of calling into the underlying file object,
since if multiple `_SharedFile` instances are being used concurrently on
the same file, another one may have moved the real file position.
Additionally, calling into the underlying `tell` may expose thread
safety issues in the underlying file object because it was called
without taking the lock.

bpo-46968: Fix faulthandler for Sapphire Rapids Xeon (GH-31789) (GH-31830)

In Linux kernel 5.14 one can dynamically request size of altstacksize
based on hardware capabilities with getauxval(AT_MINSIGSTKSZ).

This changes allows for Python extension's request to Linux kernel
to use AMX_TILE instruction set on Sapphire Rapids Xeon processor
to succeed, unblocking use of the ISA in frameworks.

Introduced HAVE_LINUX_AUXVEC_H in configure.ac and pyconfig.h.in
Used cpython_autoconf:269 docker container to generate configure.

[3.10] bpo-46581: Propagate private vars via _GenericAlias.copy_with (GH-31061) (GH-31821)

(Cherry-picked from 32bf3597922ac3f613989582afa2bff43bea8a2f.)

GH-26091 added the _typevar_types and _paramspec_tvars instance
variables to _GenericAlias. However, they were not propagated
consistently. This commit addresses the most prominent deficiency
identified in bpo-46581 (namely their absence from
_GenericAlias.copy_with), but there could be others.
