Deprecation: #93726 - Deprecated TypoScriptParser related properties
See forge#93726
Description
A cleanup of the backend 'Template' module leads to a deprecation of some TypoScript parser related class properties:
- TYPO3\- CMS\ - Core\ - Typo - Script\ - Parser\ - Typo - Script - Parser->break - Point - LN 
- TYPO3\- CMS\ - Core\ - Typo - Script\ - Parser\ - Typo - Script - Parser->parent - Object 
- TYPO3\- CMS\ - Core\ - Typo - Script\ - Template - Service->ext_ - constants_ - BRP 
- TYPO3\- CMS\ - Core\ - Typo - Script\ - Template - Service->ext_ - config_ - BRP 
Impact
The properties are not handled any longer and will be dropped with TYPO3 v12.
Affected Installations
It is very unlikely extensions used these properties since they were specific to the backend 'Template' module and of little use otherwise.
The extension scanner will still find usages except the 
        parent
since this property name is too generic and would trigger too many false
positive matches.
Migration
The functionality of these properties has been dropped.
