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.
