KVM: selftests: Add test to verify KVM handling of ICR
The main thing that the selftest verifies is that KVM copies x2APIC's
ICR[63:32] to/from ICR2 when userspace accesses the vAPIC page via
KVM_{G,S}ET_LAPIC. KVM previously split x2APIC ICR to ICR+ICR2 at the
time of write (from the guest), and so KVM must preserve that behavior
for backwards compatibility between different versions of KVM.
It will also test other invariants, e.g. that KVM clears the BUSY
flag on ICR writes, that the reserved bits in ICR2 are dropped on writes
from the guest, etc...
