devices: pci: pvpanic: pvpanic virtual device initial implementation

pvpanic is a simulated device through which a guest panic event could be
sent to the VMM. More details here:
https://github.com/qemu/qemu/blob/master/docs/specs/pvpanic.txt

Implement pvpanic device emulation and its pci interface.

BUG=None
TEST=Built crosvm. Ran a minimal vm to crash and verified that crosvm
receives the panic event. cargo test on devices.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
