chg: dev: Use query counters in validator code

Commit af7db8951364a89c468eda1535efb3f53adc2c1f as part of #4141 was supposed to apply the 'max-recursion-queries' quota to validator queries, but the counter was never actually passed on to 'dns_resolver_createfetch()'. This has been fixed, and the global query counter ('max-query-count', per client request) is now also added.

Related to #4980

Merge branch '4980-pass-counters-in-validator-createfetch' into 'main'
