Currently you need to use `opendir` and then call `getMetadata` for
every file, which adds overhead because most storage backends already
get the metadata when doing the `opendir`.
While storagebackends can (and do) use caching to relief this problem,
this adds cache invalidation dificulties and only a limited number of
items are generally cached (to prevent memory usage exploding when
scanning large storages)
With this new methods storage backends can use the child metadata they
got from listing the folder to return metadata without having to keep
seperate caches.

the target storage doesn't need additional handling for wrappers as the wrappers implementation of moveFromStorage already deals with that
Any storage based on local storage isn't affected by this as local storage already has it's own way of handling with this

Fixes#11637
If we do not normalize the unjailed path we might end up with a path
like files/user/folder/. which can break on objectstores
