fix: dev: Reduce the false sharing the dns_qpcache and dns_qpzone

Instead of having many node_lock_count * sizeof(<member>) arrays, pack all
the members into a qpcache_bucket_t that is cacheline aligned to prevent
false sharing between RWLocks.

Merge branch 'ondrej/prevent-nodelock-false-sharing' into 'main'
