* fix(build): Restore erroneously-deleted filter function This was deleted in PR #7406 as it was mainly being used to filter core/ vs. test/mocha/ deps into separate deps files - but it turns out also to be used for filtering error messages too. Oops. * refactor(tests): Migrate advanced compilation test to ES Modules * refactor(build): Migrate main.js to TypeScript This turns out to be pretty straight forward, even if it would cause crashing if one actually tried to import this module instead of just feeding it to Closure Compiler. * chore(build): Remove goog.declareModuleId calls Replace goog.declareModuleId calls with a comment recording the former module ID for posterity (or at least until we decide how to reformat the renamings file. * chore(tests): Delete closure/goog/* For the moment we still need something to serve as base.js for the benefit of closure-make-deps, so we keep a vestigial base.js around, containing only the @provideGoog declaration. * refactor(build): Remove vestigial base.js By changing slightly the command line arguments to closure-make-deps and closure-calculate-chunks the need to have any base.js is eliminated. * chore: Typo fix for PR #7415
