refactor: apply TYPO3 13 Rector and Fractor migrations

Automated migrations from rector.php and fractor.php (TCA, Extbase
controllers and annotations, ViewHelpers, QueryBuilder, FlexForms,
TypoScript conditions).

Plugins stay list_type plugins: Rector switched them to content
element types, which needs a tt_content migration. That is deferred to
the TYPO3 14 step, where list_type is removed.
