Subject: [PATCH] query-request: add formatter for query-request.hh types

before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.

in this change, we define formatters for following types

* query::specific_ranges
* query::partition_slice
* query::read_command
* query::forward_request
* query::forward_request::reduction_type
* query::forward_request::aggregation_info
* query::forward_result::printer

Refs #13245
