chg: dev: Prevent false sharing by aligning some zone and db fields

The zone refcount, zone dblock, db refcount and db lock are pretty contended in setups serving few big zones, such as TLDs.

We add alignment to both in order to prevent false sharing between them.

Merge branch 'alessio/aligned-atomics-v4' into 'main'
