Bug 1425310 - Implement modulepreload for link rel. r=yulia,smaug,jonco
Does perform the optional step of fetching descendants and linking: https://html.spec.whatwg.org/multipage/webappapis.html#fetching-scripts:fetch-the-descendants-of-and-link-a-module-script-2 Partially implements some new destinations ("as" attribute values) for modulepreload only (not for preload or link attribute reflection) Differential Revision: https://phabricator.services.mozilla.com/D172368
