KVM: selftests: Add VGICv5 IST attribute tests
Add API coverage for the VGICv5 IST attribute group. This does not
test that IST save/restore preserves interrupt state; it only checks
the attribute plumbing and the cases KVM must reject before the
end-to-end restore path can rely on the interface.
Verify that KVM reports the IST attribute group, rejects unknown
attributes, rejects save/restore before initialization, rejects bad
userspace pointers, and rejects IST restore after the VM has run.
Also cover the userspace IST descriptor validation: a VM with SPIs
must provide a SPI IST buffer of the expected size, and LPI storage
must not be supplied when no LPI IST is configured.
