pvpanic: Advertise the PVPANIC_CRASHLOADED event support
Advertise both types of events as supported when the guest OS
queries the pvpanic device. Currently only PVPANIC_PANICKED is
exposed; PVPANIC_CRASHLOADED must also be advertised, but only on
new machine types.
Fixes: 7dc58deea79a ("pvpanic: implement crashloaded event handling")
