This bug implements and opens window.print() for Android in Nightly. Adds "GeckoView:DotPrintRequest" and "GeckoView:DotPrintFinish" events. GeckoView:DotPrintRequest requests a PDF of the current window.print page for Android to print. GeckoView:DotPrintFinish releases the static browser clone created by window.print. PDF generation was additionally adjusted to get the expected canonical browser context when printing iframes. Differential Revision: https://phabricator.services.mozilla.com/D171159
