runtime: rename ncpu to numCPUStartup
ncpu is the total logical CPU count at startup. It is never updated. For #73193, we will start using updated CPU counts for updated GOMAXPROCS, making the ncpu name a bit ambiguous. Change to a less ambiguous name. While we're at it, give the OS specific lookup functions a common name, so it can be used outside of osinit later. For #73193.
