Doug Parker 7c1991048b refactor(zone.js): wrap Zone.__load_patch calls in exported functions (#53443)
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.
