fix(cpus/denver): use CPU_NO_EXTRA3_FUNC for all variants

Denver CPUs use the same workaround for CVE-2017-5715 and CVE-2022-23960
vulnerabilities. The workaround for CVE-2017-5715 is always enabled, so
all Denver variants use CPU_NO_EXTRA3_FUNC as a placeholder for the
mitigation for CVE-2022-23960. This patch implements the approach.
