J. Nick Koston 14c54597ce [binary_sensor] Make set_new_state non-virtual, add on_state_changed_ hook
set_new_state is only called internally. Making it non-virtual
eliminates a vtable entry and allows the compiler to inline it.

BinarySensor now overrides on_state_changed_() for logging and
ControllerRegistry notification instead of overriding set_new_state.
