Checking if a given sector is aligned to a zone is a very common
operation that is performed for zoned devices. Add
blk_queue_zone_aligned helper to check for this instead of opencoding it
everywhere.

The helper is made to be generic so that it can also check for alignment
for non non-power-of-2 zone size devices.

As the existing deployments of zoned devices had power-of-2
assumption, power-of-2 optimized calculation is done for devices with
power-of-2 zone size
