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.

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.

[3.10] bpo-46940: Don't override existing AttributeError suggestion information (GH-31710) (GH-31724)
When an exception is created in a nested call to PyObject_GetAttr, any
external calls will override the context information of the
AttributeError that we have already placed in the most internal call.
This will cause the suggestions we create to nor work properly as the
attribute name and object that we will be using are the incorrect ones.
To avoid this, we need to check first if these attributes are already
set and bail out if that's the case..

* `precision` field is a decimal integer
* clarify that stated limitations are on presentation type
rather than input value type. Especially misleading is
"precision is not allowed for integer values", since integer
value input to a format like `.1f` is fine.
* regarding max field size, replace "non-number" with "string",
which is the only non-numeric presentation type

bpo-45863: tarfile: don't zero out header fields unnecessarily (GH-29693)
Numeric fields of type float, notably mtime, can't be represented
exactly in the ustar header, so the pax header is used. But it is
helpful to set them to the nearest int (i.e. second rather than
nanosecond precision mtimes) in the ustar header as well, for the
benefit of unarchivers that don't understand the pax header.
bpo-46678: Fix Invalid cross device link in Lib/test/support/import_helper.py (GH-31204) (GH-31207)
In `Lib/test/support/import_helper.py`, the function `make_legacy_pyc` makes a call to `os.rename` which can fail when the source and target live on different devices. This happens (for example) when `PYTHONPYCACHEPREFIX` is set to a directory anywhere on disk, while a ramdisk is mounted on `/tmp` (the latter of which is the default on various Linux distros). Replacing `os.rename` with `shutil.move` fixes this.
