SystemUI: Add config to disable HumanInteractionClassifier 

On some devices HumaInteractionClassifier is more of a nuisance than a
useful feature by making the screen hard to unlock at random. Add a
config that allows to define the default state of HIC, which currently
can only be disabled running the following command:

  settings put global HIC_enable 0
