HV: CAT: support config CAT from acrn_vm_config

Browse Source 
When CAT is supported, UOS can setup acrn_vm_config.clos, to use CAT
feature. Eg.,

struct acrn_vm_config vm_configs[CONFIG_MAX_VM_NUM] = {
    {
        .guest_flags |= CLOS_REQUIRED,
        .clos = 1,
    },
};

sanitize_vm_config() will check if CAT is supported and
vm_configs.clos is valid.
