KVM: VMX: Define VMCS-to-EVMCS conversion for the new fields
Enlightened VMCS v1 definition was updated with new fields, support
them in KVM by defining VMCS-to-EVMCS conversion.
Note: SSP, CET and Guest LBR features are not supported by KVM yet and
the corresponding fields are not defined in 'enum vmcs_field', leave
them commented out for now.
