Ivy uses R3Injector, but we are currently pulling in both the StaticInjector (View Engine injector) and the R3Injector when running with Ivy. This commit adds an ivy switch so calling Injector.create() pulls in the correct implementation of the injector depending on whether you are using VE or Ivy. This saves us about 3KB in the bundle.
