Add pvpanic device to monitor virtual machine system panics. Add pvpanic
field in virtual machine configuration files, allowing to choose the ISA
or the PCI variant of the pvpanic device.

Add basic structure for adding and editing a pvpanic device, allowing to
monitor guest system panics through the pvpanic device. Add an
architecture-aware pvpanic device type option since arm64 does not
support pvpanic ISA device.
