feat(upgrade): use ComponentFactory.inputs/outputs/ngContentSelectors

DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
  are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
  ComponentFactory.ngContentSelectors instead.
