feat(core): expose inputs, outputs and ngContentSelectors on ComponentFactory.

E.g. for a component like this:
```
@Component({
  template: ‘<ng-content select=“child”></ng-content>’
})
class MyComp {
  @Input(‘aInputName’)
  aInputProp: string;

  @Output(‘aEventName’)
  aOuputProp: EventEmitter<any>;
}
```

the `ComponentFactory` will now contain the following:
- `inputs = {aInputProp: ‘aInputName’}`
- `outputs = {aOutputProp: ‘aOutputName’}`
- `ngContentSelectors = [‘child’]`
