build: remove windows runfile workaround

* Since bazel-contrib/rules_nodejs@1f97eb6 landed, we can safely remove the workaround by updating the NodeJS and TypeScript Bazel rules.
* Also we are creating our own `getFileContent` testing method because it's not guaranteed that the internal testing utilities from `@schematics/angular` always stay the same. Additionally this works around an issue where `test` folders are excluded in the Bazel managed deps by default.
