This removes top-level side effects from each of these files and drops the dependency on global `Zone`, instead allowing it to be provided to each patch as a parameter. Most of these are pure mechanical transformations. A couple notable files which were somewhat unique: * `async-test.ts`, `fake-async-test.ts`, and `wtf.ts` had unique IIFE usage and patch `Zone` itself. This removes the IIFE and exports the function instead. * `jest.ts` and `jasmine.ts` have a unique `jest` global usage which needs to be declared. PR Close #53443
