Lukasz Lenart b936fcbf8b WW-5621 Harden XML parsers against Entity Expansion (Billion Laughs) attacks (#1643)
Backport of apache/struts#1642 from Struts 7 to Struts 6.

Modern JDKs (7u45+) already protect against this attack with a built-in
64K entity expansion limit. These changes add defense-in-depth hardening
and remove unnecessary attack surface.

- Enable FEATURE_SECURE_PROCESSING in DomHelper SAX parser
- Enable FEATURE_SECURE_PROCESSING in DigesterDefinitionsReader
- Remove unused parseStringAsXML feature from StringAdapter to eliminate
  a theoretical XML Entity Expansion vector
- Deprecate setParseStringAsXML() and getParseStringAsXML() for removal
- Add Billion Laughs protection tests for DomHelper and DigesterDefinitionsReader
