Fixing two tests that fail on Mac:

1. tests/test_cpu_load.py - allow for `AppleSiliconChip` CPU type.
1. tests/test_unsupported_gpu.py - don't bother running this on Mac
   since NVML is not supported and the test becomes flaky becomes
   sometimes the AppleSiliconChip GPU power consumption is close
   enough to zero to pass, and sometimes it isn't.
