Implement the GCIE_LEGACY capability as a system feature to be able to check for support from KVM. The type is explicitly ARM64_CPUCAP_EARLY_LOCAL_CPU_FEATURE, which means that the capability is enabled early if all boot CPUs support it. Additionally, if this capability is enabled during boot, it prevents late onlining of CPUs that lack it, thereby avoiding potential mismatched configurations which would break KVM.
