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\TypoScript\Parser\TypoScriptParser->breakPointLN

• TYPO3\CMS\Core\TypoScript\Parser\TypoScriptParser->parentObject

• TYPO3\CMS\Core\TypoScript\TemplateService->ext_constants_BRP

• TYPO3\CMS\Core\TypoScript\TemplateService->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 parentObject since this property name is too generic and would trigger too many false positive matches.

Migration

The functionality of these properties has been dropped.
