Added * Add a new CPU template called `T2S`. This exposes the same CPUID as `T2` to the Guest and also overwrites the `ARCH_CAPABILITIES` MSR to expose a reduced set of capabilities. With regards to hardware vulnerabilities and mitigations, the Guest vCPU will apear to look like a Skylake CPU, making it safe to snapshot uVMs running on a newer host CPU (Cascade Lake) and restore on a host that has a Skylake CPU. Fixed * Make the `T2` template more robust by explicitly disabling additional CPUID flags that should be off but were missed initially or that were not available in the spec when the template was created.
