x86/cpuid: Rename hypervisor_cpuid_base()/for_each_possible_hypervisor_cpuid_base() to cpuid_base_hypervisor()/for_each_possible_cpuid_base_hypervisor()
In order to let all the APIs under <cpuid/api.h> have a shared "cpuid_" namespace, rename hypervisor_cpuid_base() to cpuid_base_hypervisor(). To align with the new style, also rename: for_each_possible_hypervisor_cpuid_base(function) to: for_each_possible_cpuid_base_hypervisor(function) Adjust call-sites accordingly.
