[TASK] Use prepared statement in BackendUtility::getPageForRootline

The function is already caching the result for individual pages.
Still it is called for a lot of pages, so even more speed
can be gained by also re-using the database statement.

Specifically the page-tree rendering time reduces a lot with this.
