[FEATURE] Add Event to modify the results of the PageTreeRepository

A new PSR-14 Event "AfterRawPageRowPreparedEvent" is added
to allow to filter out, or remove or re-sort items / children
for the page tree in the TYPO3 Backend.

This is typically the case for e.g. sorting subpages
within a page by e.g. the creation date (news as pages).
