O-Subject: [RHEL8.2.1 AV qemu-kvm PATCH 4/4] target/i386: Add missed features to Cooperlake CPU model
Bugzilla: 1769912

From: Xiaoyao Li <xiaoyao.li@intel.com>

It lacks VMX features and two security feature bits (disclosed recently) in
MSR_IA32_ARCH_CAPABILITIES in current Cooperlake CPU model, so add them.
