Feature: #99165 - Add "Edit Metadata" button to element information view

See forge#99165

Description

A new button Edit Metadata has been added to the element information view of files. It allows to directly edit corresponding Metadata without leaving the context. The element information view for files can be accessed via the context menu or via the secondary action of files in any file listing, for example, in the File > Filelist module or the File selector.

Impact

It's now possible to edit a file's Metadata directly in the element information view, which improves the UX as the context is not lost.
