virt-what-cvm: probe for SNP/HCL on HyperV/Azure via CPUID
When running a confidential VM on Azure (HyperV) we can probe
CPUID leaf 0x40000003 to detect if VM isolation is present,

Introduce 'virt-what-cvm' program
The 'virt-what' program prints facts that reflect the hypervisor that
the guest is running under.
The new complementary 'virt-what-cvm' program prints facts that reflect
the confidential virtualization technology the guest is running under,
if any.
It is kept as a separate tool, rather than incorporating the facts into
'virt-what' output because it is considering a different aspect of the
virtualization. Furthermore there are specific security concerns around
the usage of facts reported by 'virt-what-cvm'.
The tool has been tested in a number of environments
* Azure confidential guest with AMD SEV-SNP (GA)
* Azure confidential guest with Intel TDX (technology preview)
* Fedora 37 QEMU/KVM guest with AMD SEV (GA)

information indicates the hardware OEM is Alibaba.
However 'make check' would hang if 100.100.100.200 doesn't immediately
reject the connection. I found that GCE is such an environment where
connecting to this address would hang rather than reject. GCE does
not have Alibaba hardware of course, but when doing 'make check' we
fake dmidecode data.

Detect KVM property when running on POWER (RHBZ#1455676).
QEMU on ppc64 adds an additional property in the device tree if
running with KVM, so you could check that property for the string
"linux,kvm" to see if KVM is enabled:
0000000: 6c69 6e75 782c 6b76 6d00 linux,kvm.

qemu/kvm: dmidecode: look for 'KVM'
We can check the product name for 'KVM' to determine if we're
accelerated. This only works for arm/aarch64 targets boot with
AAVMF and on RHEL x86 targets (which already have KVM in the cpuid
leaf), but it doesn't hurt to try on all.

qemu/kvm: try dmidecode on all targets
Looking at "$dmi" on targets that don't support dmidecode is
harmless. Furthermore it works, not only for arm targets, but
also pc, so move it out of the 'if arm' block.

Detect QEMU/KVM on ARM guests that have been boot with ACPI, i.e.
