Fix GH-22167: reject out-of-range SOAP schema integers

[LamentXU123]

Fixed #22167

I also add logic to deal with numeric-strings. Now, both 2147483648 and 2147483648abc will not be accepted (also added tests). Other behaviors remain the same.

I don't sure if we can write the helper function in simpler ways using existing Zend API.

High level note ; I'd target master rather than 8.4. It's a correct change, but it turns input that currently parses (silently truncated by atoi) into a fatal SOAP-ERROR, so a WSDL
that works today could break on a patch release. That kind of stricter parsing belongs in the next minor where we can note it in UPGRADING; on a stable branch it's a
behavior change we'd rather avoid.

This is rather like a new feature than a bug fix, we have lots of similar fixes before (i.e. rejecting NUL bytes in some functions) targeting the master branch so this should be targeting it too.

take your time I ll (re)review it saturday at earliest.
