Subject: [PATCH] Add a "supportsPrinting" viewer-option (bug 1957401)

This will allow us to respect the `print.enabled` Firefox preference, by extending [this method](https://searchfox.org/mozilla-central/rev/56117379696ea0cffb94cd09c14cd022a8c5e4e8/toolkit/components/pdfjs/content/PdfStreamConverter.sys.mjs#426-453), which will hide the toolbar and secondaryToolbar print-buttons.
