The new Files Experience should be available inline in pages

The deprecated Office Connector allows users to display files and documents inline, which means that users can read documents in context with the rest of the page.

With the new files preview in 5.7, using the new files experience forces files to be opened in a lightbox, which means it's impossible to view the rest of the page and the files at the same time.

We should provide the option to display the files experience in line. This is particularly important for complex documents that do not render in the Office Connector (and since the Office Connector is deprecated, display bugs won't be fixed because the Files experience renders them correctly).
