Part of "target-i386: Add way to expose VMWare CPUID"

Also known as Paravirtualization vendor.
This is EBX, ECX, and EDX data for 0x40000000.

QEMU knows this is KVM_CPUID_SIGNATURE (0x40000000).

This is based on:

Microsoft Hypervisor CPUID Leaves:

Linux kernel change starts with:

VMware documention on CPUIDs (Mechanisms to determine if software is
running in a VMware virtual machine):
