misc: pvpanic: move bit definition to uapi header file Some processes outside of the kernel(Ex, QEMU) should know what the value really is for, so move the bit definition to a uapi file.

misc/pvpanic: use bit macros The macros are easier to read.

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").
