The hw.cpufrequency sysctl, which we use to obtain the CPU frequency on macOS, is not available when running on Apple Silicon, and as a consequence we currently report an error whenever such information is requested.

The virNodeInfo.mhz field, where the CPU frequency gets stored, is documented as being zero when the information could not be obtained, and we already do that for Linux on aarch64. Extend this behavior to macOS on Apple Silicon.
