Feature: #78347 - Add StdWrap properties to FilesProcessor

See forge#78347


StdWrap properties have been added to FLUIDTEMPLATEs FilesProcessor the same way as in FilesContentObject. That way you can implement slide-functionality on rootline for file resources.

TypoScript dataProcessing example with FilesProcessor

page.10.dataProcessing {
  10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
  10 {
   references.data = levelmedia: -1, slide
   as = myfiles


The FilesProcessor can slide up and down the rootline to collect images for FLUID templates. One usual feature is to use images attached to pages and use them up and down the page tree for header images in frontend.
