[api-minor] Support the Content-Disposition filename in the Firefox PDF Viewer (bug 1694556, PR 9379 follow-up)

Browse source 
As can be seen [in the mozilla-central code](https://searchfox.org/mozilla-central/rev/a6db3bd67367aa9ddd9505690cab09b47e65a762/toolkit/components/pdfjs/content/PdfStreamConverter.jsm#1222-1225), we're already getting the Content-Disposition filename. However, that data isn't passed through to the viewer nor to the `PDFDataTransportStream`-implementation, which explains why it's currently being ignored.

*Please note:* This will also require a small mozilla-central patch, see https://bugzilla.mozilla.org/show_bug.cgi?id=1694556, to forward the necessary data to the viewer.
