Define 'resolve()' function on import.meta object on browser. Add mochitests for import.meta.resolve, as some of the wpt tests for import.meta.resolve cannot be run due to some bugs in wpt testing framework. See https://bugzilla.mozilla.org/show_bug.cgi?id=1785806 Differential Revision: https://phabricator.services.mozilla.com/D154105
