[BUGFIX] Show fields for files/folders in ElementInformationController

The changes made to the ElementInformationController in #88901 had a few
problems and regressions:

- A lot of information for files and folders, that has previously been
shown, was now missing.
- Metadata for files was missing as well, because this information is
saved in a separate table. (sys_file_metadata)

This patch brings back all the lost information. Also, the Metadata of
a file can now be viewed in the ElementInformation window as well.
