On macOS this goes through NSWorkspace's setDefaultApplication API (macOS 12+) and resolves once the OS consent prompt completes. Adds the supporting isDefaultHandlerFor and canSetAsDefaultPDFHandler members and records the set_default_pdf_handler_attempt telemetry on macOS.

Attachment: Bug 2047633 - Offer setting Firefox as the default PDF handler from about:pdf on macOS. r?mossop

Enable the about:pdf set-as-default-PDF-handler promo on macOS and hide it once Firefox becomes the default.
