Botond Dénes 5e422ceefb cql3/query_processor: for_each_cql_result(): move func to the coro frame
Said method has a func parameter (called just f), which it receives as
rvalue ref and just uses as a reference. This means that if caller
doesn't keep the func alive, for_each_cql_result() will run into
use-after-free after the first suspention point. This is unexpected for
callers, who don't expect to have to keep something alive, which they
passed in with std::move().
Adjust the signature to take a value instead, value parameters are moved
to the coro frame and survive suspention points.
Adjust internal callers (query_internal()) the same way.

There are no known vulnerable external callers.
