Move statsd (and tests) to libbinder_ndk

Major changes include:
    - Removing unused permission checks within StatsService. These
      include ENFORCE_DUMP_AND_USAGE_STATS, checkDumpAndUsageStats,
      kOpUsage, and kPermissionUsage.
    - Converting from sp to shared_ptr
    - Using libbinder_ndk functions instead of libbinder functions
      (e.g. for installing death recipients, getting calling uids, etc.)
        - New death recipients were added in StatsService,
          ConfigManager, and SubscriberReporter.
    - Using a unique token (timestamp) to identify shell subscribers
      instead of IResultReceiver because IResultReceiver is not exposed by
      libbinder_ndk. Currently, statsd cannot detect if perfd dies; we
      will fix that later.
