KVM: VMX: Detect Tertiary VM-Execution control when setup VMCS config
Check VMX features on tertiary execution control in VMCS config setup.
Sub-features in tertiary execution control to be enabled are adjusted
according to hardware capabilities although no sub-feature is enabled
in this patch.
EVMCSv1 doesn't support tertiary VM-execution control, so disable it
when EVMCSv1 is in use. And define the auxiliary functions for Tertiary
control field here, using the new BUILD_CONTROLS_SHADOW().
