Deprecation: #83118 - DeleteClause methods deprecated 

See forge#83118

Description 

The PHP methods PageRepository::deleteClause() and BackendUtility::deleteClause() have been marked as deprecated, as all database queries are now put through Doctrine DBAL's restriction functionality.

Impact 

Calling one of the two methods above will trigger a deprecation log entry.

Affected Installations 

Any TYPO3 extension using any of the two methods above.

Migration 

Migrate to Doctrine DBAL and use the new Database API (ConnectionPool, QueryBuilder) to access the database with the DeletedRestriction class.
