cmsdk: Add support for more preference constraints

 * Add support for negation- prefix with !
 * Add requiresAction constraint, which checks if an application is
   available to resolve the given action
 * Fix issues with operations order
 * Add flag to remove a preference if it's intent can't be resolved
 * Add helper to allow setting minLines of a preference, since it's
   common for things to get weird with the kinds of behavior we
   are introducing everywhere
 * Add support for nuking *other* preferences. For example with
   Doze, many devices have custom features and a extra_settings
   panel which is redundant with the switch. Now we can trivially
   override the one we don't want.
