core_type: refactor intel core type detection to account for another output format

[17314642]

Previous implementation expects that files cpu_atom and cpu_core will have range output like this: 0-9
Turns out there is another format:

❯ cat /sys/devices/cpu_core/cpus
0-1,3,6,8,10
user@nv54 ~ 
❯ cat /sys/devices/cpu_atom/cpus 
12-21
user@nv54 ~ 
❯ 

It's both ranges and separate cores
