panic: Publish EC_HOST_EVENT_PANIC on panic
Publish EC_HOST_EVENT_PANIC when a panic occurs.
The kernel may use this event to clean up before the system is reset
(e.g. sync the drive).
This will be a no-op if the kernel doesn't handle it.
BUG=b:258195448
BRANCH=None
TEST=Observe event in kernel. Pass panic_event unit test.
