The current version of XZ used by Windows and macOS (5.2.x) is no longer supported. We should update to 5.8.1 so that we are on a supported branch.
The macOS installer uses 5.2.3

I have a draft PR to cpython-source-deps to import 5.8.1 python/cpython-source-deps#44, but given the large version change the MSVC build definition will likely need some updating too (see e.g. #140818).
