misc/pvpanic: add shutdown event definition

Browse source 
Shutdown requests are normally hardware dependent.
By extending pvpanic to also handle shutdown requests, guests can
submit such requests with an easily implementable and cross-platform
mechanism.

The event was added to the specification in qemu commit
73279cecca03 ("docs/specs/pvpanic: document shutdown event").
