We'll add a new bare CPU type that won't have any default priv_ver. This means that the CPU will default to priv_ver = 0, i.e. 1.10.0. At the same we'll allow these CPUs to enable extensions at will, but then, if the extension has a priv_ver newer than 1.10, we'll end up disabling it. Users will then need to manually set priv_ver to something other than 1.10 to enable the extensions they want, which is not ideal. Change the setter() of extensions to allow user enabled extensions to bump the priv_ver of the CPU. This will make it convenient for users to enable extensions for CPUs that doesn't set a default priv_ver. This change does not affect any existing CPU: vendor CPUs does not allow extensions to be enabled, and generic CPUs are already set to priv_ver LATEST.
