ci: use manual caching with actions/cache (#16788)

* ci: use manual caching with actions/cache

use os agnostic cache key
only cache pkg mod cache

* ci: enable enableCrossOsArchive

by default cache won't be shared across os

enable it so we can reuse the go module cache

(cherry picked from commit bac9fec)
