ec/lenovo/h8: Add panic method
Add two additional LED IDs. Add Kconfig menu entries to allow selecting the action to execute on death. Overwrite weak die_notify method to notify user on death. Flash all LEDs and play beep code 10 depending on Kconfig options. Successfully tested on: Tested on Lenovo T500. Tested on Lenovo X200. Tested on Lenovo T430, but only LEDs are flashing.
