refactor(@angular-devkit/build-angular): ensure TS resolution cache with file replacements

When overriding module resolution on a TypeScript Host object, TypeScript will not
automatically create a resolution cache for the Host. Within the application build system
the TypeScript resolution is only overrided if file replacements are used. A resolution
cache is now manually created and added to the TypeScript Host when file replacements are
present.
