npcx: watchdog: Log watchdog panic information
On EC panic events such as assertion fail, watchdog, etc. log the EC
state to our persistent panic log so that it can be retrieved later.
BUG=chrome-os-partner:57794
BRANCH=Kevin
TEST=Run `crash watchdog` on kevin, then `panicinfo` on subsequent boot.
Verify saved panic log matches watchdog dump.
