Breaking: #102590 - TSFE->generatePage_preProcessing() removed 

See forge#102590

Description 

Frontend-related method TypoScriptFrontendController->generatePage_preProcessing() has been removed without substitution.

Impact 

Calling the methods will raise a fatal PHP error.

Affected installations 

There is little to no need for extensions to call or override this method and it should have been marked as @internal already. It was part of a removed "safety net" when extensions did set TypoScriptFrontendController->no_cache to false after it has been set to true already, which is not allowed.

Migration 

No migration, do not call the method anymore.
