feat(directives): remove the @Controller directive

Completely remove the deprecated Controller directive.

Major update to the demos to use setRootContext (where applicable) and
to move to Components for the beefier demos (bouncing balls and form).

so that rootContext have Map interface. The work arounds will disappear
after the context is set to the component.

Closes #1401
