feat(render): don’t use the reflector for setting properties

BREAKING CHANGES:
- host actions don't take an expression as value any more but only a method name,
  and assumes to get an array via the EventEmitter with the method arguments.
- Renderer.setElementProperty does not take `style.`/... prefixes any more.
  Use the new methods `Renderer.setElementAttribute`, ... instead

Part of #2476
Closes #2637
