Add empty implementation of ShadeController
Variants without shades want this, so there should be only one, and
it should be in the shade package to make updates not require topics.
Also adds some default methods to ShadeController to reduce the size
of ShadeControllerEmptyImpl and deemphasize ShadeController methods
that are too tied to implementation details of ShadeControllerImpl.
Test: presubmits are sufficient
