This isn't a good fit with consistency with controllers. Discussed with
@DamianEdwards and we agreed to remove this for now and bring it back in
the future if there's a real need for it.
This changeset reckonciles the binding work we did for pages with
controllers.
A quick summary:
- Moves [BindProperty] to the MVC namespace (#6401)
- Makes [FromRoute] and friends behave consistently (#6402)
- Makes [BindProperty] work with controllers (untracked)
