Calixte Denizet 567f585def Add a pref-controlled method to notify embedders that mozPrintCallback has completed (bug 2036265)
Adds a `postMessageAfterPrintCallback` browser option (off by default).
When enabled by Firefox, the print service posts "ready" or "error" to
the window after each page's mozPrintCallback resolves, so embedders
(e.g. print-preview test harnesses) can observe when rendering is done.

Upstreams the viewer-side portion of Phabricator D297837.
