google/chromeos: Support AP watchdog flag from Chrome EC
After ChromiumOS CL:1293132 and CL:1295890, Chrome EC can store the flag
telling if the last reboot was triggered by AP watchdog for some boards
(e.g., Kukui).
This CL adds a new function google_chromeec_get_ap_watchdog_flag(),
which reads the AP watchdog flag from Chrome EC, and updates the tables
of reset causes and reset flags.
A new Kconfig option CHROMEOS_USE_EC_WATCHDOG_FLAG is added for
elog_handle_watchdog_tombstone() to determine if watchdog reset was
triggered by the AP watchdog flag from EC instead of the tombstone in
AP.
