A bug in the wptsync caused us to miss some pushes during recent updates. This commit copies the head of wpt at the specified revision over and re-applies local patches that weren't in that revision. That means we should be able to resume normal syncs after fixing the bug. wpt-head: 55e3f8d27d6be17fa75bebe426c39cc51b3b26d4 wpt-type: landing Differential Revision: https://phabricator.services.mozilla.com/D90823
