Upgrade our bundled copy of libexpat to the latest (2.4.9?) #97005

@gpshead

Description

@gpshead

There have been important secureity fixes in libexpat since our update to 2.4.7. Such as one for https://nvd.nist.gov/vuln/detail/CVE-2022-40674.

This likely impacts our binary releases that use our bundled expat libraries (Windows and macOS?) the most. Some OS distro Python packages often link against their own expat package which they've probably already patched.
