Feature: #89090 - Reports for conflicting redirects

See forge#89090


A new Symfony command has been introduced that detects redirects that conflict with pages. The command is marked as schedulable, thus it can be created as a scheduler task.


If EXT:scheduler and EXT:reports are installed, the redirect status may be checked and presented as an additional report.

The command may be executed via CLI by invoking ./typo3/sysext/core/bin/typo3 redirects:checkintegrity. The command accepts the option --site which takes a site identifier to take the pages of that site into consideration only.
