- update `autoCompletion\perl.xml` to auto-complete on the new keywords/built-in-functions/pragmas
- update `langs.model.xml` to syntax-highlight on the new keywords/built-in-functions/pragmas
Close#14191
1. Added xml syntax check via python script just for the win32 debug build because there already the functionlist check happens.
2. Fixed an issue found for perl.
Fix#9330, close#9339
