bpo-46784: Add newly exported expat symbols to the namespace. (GH-31397)
The libexpat 2.4.1 upgrade from  introduced the following new exported symbols:

* `testingAccountingGetCountBytesDirect`
* `testingAccountingGetCountBytesIndirect`
* `unsignedCharToPrintable`
* `XML_SetBillionLaughsAttackProtectionActivationThreshold`
* `XML_SetBillionLaughsAttackProtectionMaximumAmplification`

We need to adjust [Modules/expat/pyexpatns.h](https://github.com/python/cpython/blob/master/Modules/expat/pyexpatns.h)

(The newer libexpat upgrade  has no new symbols).

*
* Namespace all expat exported symbols to avoid dynamic loading symbol
* collisions when embedding Python.
*
* The Problem:
* - you embed Python in some app
* - the app dynamically loads libexpat of version X
* - the embedded Python imports pyexpat (which was built against
* libexpat version X+n)
* --> pyexpat gets the expat symbols from the already loaded and *older*
* libexpat: crash (Specifically the crash we observed was in
* getting an old XML_ErrorString (from xmlparse.c) and then calling
* it with newer values in the XML_Error enum:
*
* // pyexpat.c, line 1970
* ...
* // Added in Expat 1.95.7.
* MYCONST(XML_ERROR_UNBOUND_PREFIX);
* ...
*
*
* The Solution:
* Prefix all exported symbols with "PyExpat_". This is similar to
* what Mozilla does for some common libs:
* http://lxr.mozilla.org/seamonkey/source/modules/libimg/png/mozpngconf.h#115
*
* The list of relevant exported symbols can be had with this command:
*
nm pyexpat.so \
| grep -v " [a-zBUA] " \
| grep -v "_fini\|_init\|initpyexpat"
*
* If any of those symbols are NOT prefixed with "PyExpat_" then
* a #define should be added for it here.
