Expose session based authentication through mount point type

[juliusknorr]

With this apps can check whether an external storage mountpoint uses credentials stored in the session and can act upon that. An example scenario would be Collabora/ONLYOFFICE or the direct editing endpoint on mobile/desktop clients that cannot be used with session based auth since the session is not available in the unauthenticated requests.

Reference implementation for Collabora nextcloud/richdocuments#1178

There seems to be some code in place where for the mount root 'external-root' is set for this, but I cannot figure out currently where. Maybe @icewind1991 knows, since this seems to be one thing that doesn't work anymore with this change.

I'm not a fan of re-using the mount point field for this, since it can cause issues for code relying on the values of that field.

Adding a separate field would be my preference

Yes, I cleaned that up now.
