Differences from qemu:
* "vmx-ept-uc" (bit 8) and "vmx-ept-wb" (bit 14) are not added to
qemu's list of named features yet, but used in several qemu cpu
models never the less. Add to libvirt regardless.
* "vmx-invvpid-single-context" (bit 41) is erroneously called
"vmx-invept-single-context" in qemu. This is the name of the
feature associated with bit 25 in both libvirt and qemu.
* "vmx-invvpid-single-context-noglobals" (bit 43) is erroneously
called "vmx-invept-single-context-noglobals". Use the correct name.

Some guest OSes require cpu features from the vmx-* family,
e.g. vmx-xsaves. Up to now, libvirt ignored these features as they
were not required yet. qemu does not automatically enable e.g.
"vmx-xsaves" when requesting "xsaves":
qmp="qemu-kvm -machine accel=kvm -nodefaults -nographic -qmp stdio"
$(qmp) <<-EOF | jq | grep "xsaves"
{ "execute": "qmp_capabilities" }
{
"execute": "query-cpu-model-expansion",
"arguments": {
"type": "full",
"model": {
"name": "Skylake-Client-v1",
"props": { "xsaves": true } `# set to "true" or "false"`
}
}
}
{ "execute": "quit" }
EOF
with xsaves "false":
"xsaves": false,
"vmx-xsaves": false,
with xsaves "true":
"xsaves": true,
"vmx-xsaves": false,
Stop ignoring vmx-* features and begin adding them to libvirt's
database.

The script that synchronizes cpu models from qemu,
sync_qemu_models_i386.py, ignores all features that begin with
"vmx-". Do the same for synchronizing cpu features so we do not
have to track irrelevant features individually.
