Cleanup: Use "region" for ARegion variable names

As proposed in T74432 and already implemented in several commits,
"region" is the preferred name for `ARegion` variables, rather than
any variant of "ar". This commit changes a few "ar" variables that have
popped up over time and also adjusted names of variants like "arnew".
