ci: dynamically match makejobs with cores 

Github-Pull: #32989
Rebased-From: 3f339e99e0

Previously jobs were running on a large multi-core server where 10 jobs
as default made sense (or may even have been on the low side).

Using hosted runners with fixed (and lower) numbers of vCPUs we should
adapt compilation to match the number of cpus we have dynamically.

This is cross-platform compatible with macos and linux only.
