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.
(cherry picked from commit 3b128c054885fe881c3b57a5978de3ea89c81a9c)
