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.

* Adjusts tests to no longer rely on CommonJS features. Switches them to
ESM
* Updates test initialization files to not double-initialize Jasmine now
that bootstrap files are loaded after Jasmine. The `jasmine.boot`
setup was hacky from `rules_nodejs` and will break in the future
regardless if we e.g. use `rules_js` with actual unmodified `jasmine`.
