This changes Angular so that it can be used without reflection (assuming a codegen for injectors).
BREAKIKNG CHANGE:
- Drops `APP_COMPONENT` provider. Instead, inject
`ApplicationRef` and read its `componentTypes` property.
- long form bootstrap has changed into the following:
```
var platform = createPlatform(ReflectiveInjector.resolveAndCreate(BROWSER_PROVIDERS));
var appInjector =
ReflectiveInjector.resolveAndCreate([BROWSER_APP_PROVIDERS, appProviders], platform.injector);
coreLoadAndBootstrap(appInjector, MyApp);
```
