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.

This commit updates the implementation of the zone.js `fs` patch to
restore the implementation of `realpath.native` and patches it as a macrotask,
along with other functions of the `fs` package. This is the only nested function
that must be patched.
