fix(@ngtools/webpack): provide a TS-like path to ngProgram.listLazyRoutes

The webpack plugin was leaking our internal Path abstraction to the Angular compiler via the `ngProgram.listLazyRoutes` call.

This Path abstraction is provided by `@angular-devkit/core` and shouldn't leak. Instead a TS-like path should be provided to the Angular program.
