ANDROID: gki_defconfig: Enable hard lockup detector

Browse Source 
Enable hard lockup detector.

This enables hard lockup detection in Android devices.  However, we'll
only enable hardlockup_panic in desktop devices (in a separate CL).

ARM64 devices prefer to use the buddy detector in case the perf detector
isn't available.

Bug: 484396742
Test: cat /proc/sys/kernel/nmi_watchdog -> 1
      echo 1 >/proc/sys/kernel/hardlockup_panic
      echo HARDLOCKUP >/sys/kernel/debug/provoke-crash/DIRECT
      adb shell getprop | grep reason
      cat /sys/fs/pstore/console-ramoops-0
