[3.11] gh-115398: Expose Expat >=2.6.0 reparse deferral API (CVE-2023-52425) (GH-115623) (#116268) 
Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425) by adding five new methods:

- `xml.etree.ElementTree.XMLParser.flush`
- `xml.etree.ElementTree.XMLPullParser.flush`
- `xml.parsers.expat.xmlparser.GetReparseDeferralEnabled`
- `xml.parsers.expat.xmlparser.SetReparseDeferralEnabled`
- `xml.sax.expatreader.ExpatParser.flush`

Based on the "flush" idea from #115138 (comment) .

- Please treat as a security fix related to CVE-2023-52425.

(cherry picked from commit 6a95676)
(cherry picked from commit 73807eb)

The Python C API
================

The C API is divided into three sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/internal/``: The internal API

Information on changing the C API is available `in the developer guide`_
