[3.14] gh-90949: add Expat API to prevent XML deadly allocations (CVE-2025-59375) (GH-139234) (#139359)
* [3.14] gh-90949: add Expat API to prevent XML deadly allocations (CVE-2025-59375) (GH-139234)

Expose the XML Expat 2.7.2 mitigation APIs to disallow use of
disproportional amounts of dynamic memory from within an Expat
parser (see CVE-2025-59375 for instance).

The exposed APIs are available on Expat parsers, that is,
parsers created by `xml.parsers.expat.ParserCreate()`, as:

- `parser.SetAllocTrackerActivationThreshold(threshold)`, and
- `parser.SetAllocTrackerMaximumAmplification(max_factor)`.
