getCpuName() working properly only on x86 cpus

[AdrianoDee]

While running a CMS wfs on ARM I noticed that the CPU informations are not available

%MSG-i ThreadStreamSetup:  (NoModuleName) 10-Sep-2024 12:41:38 CEST pre-events
setting # threads 8

AlpakaServiceSerialSync succesfully initialised.
Found 1 device:
  - <unknown: CPU>

and it's related to how getCpuName() is implemented (for x86 only if I understand well). In general I think it would be nice to have this expanded to other architectures.
