Like Chromium, use the undocumented rosetta_translate_binaries function from libRosetta.dylib to pre-translate XUL and the plugin file at browser startup to reduce translation delays incurred when starting an x64 plugin process. All changes #ifdef'd to Mac ARM64. Differential Revision: https://phabricator.services.mozilla.com/D97105
