misc/pvpanic: add shutdown event definition

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").
