Renaming: "Query Result Cache" --> "Query Cache"
Reasons:

- The cache will at some point store intermediate results as opposed to
  only query results. We should change the terminology now without
  having to worry about backward compat.

- Equivalent caches in MySQL (1) and Starrocks (2) are called "query
  cache".

- The new name is ca. 13.8% more catchy.

(2) https://docs.starrocks.io/en-us/2.5/using_starrocks/query_cache

1a8437f2c9 Add ability to ignore unknown keys in JSON object for named tuples
This can be useful in case your input JSON is complex, while you need
only few fields in it.

This behaviour is controlled by the
input_format_json_ignore_unknown_keys_in_named_tuple setting name, that
is turned OFF by default.

This will, almost, allow to parse gharchive dataset without jq. "almost"
because of two things:
- Tuple cannot be Nullable, so such keys with Tuple type in ClickHouse
  cannot be `null` in JSON
- You cannot use dot.dot notation to extract columns for file() engine,
  only tupleElement()

Untangle query result cache settings
This PR modularizes the configuration options of the query result cache
(QRC).

1. Add a feature toggle "allow_experimental_query_result_cache = false"
   which controls whether the experimental QRC can be used at all. This
   configuration option will be removed once the QRC becomes
   non-experimental.

2. Modularize the existing two configuration settings
   "enable_experimental_query_result_cache" and
   "enable_experimental_query_result_cache_passive_usage" into three
   orthogonal settings:

   - "use_query_result_cache = false" controls whether a query (or all
     queries of the session) utilize the query result cache

   - settings "use_query_result_cache_passive_usage = true" and
     "use_query_result_cache_active_usage = true" control the way a
     query (or all queries of the session) utilize the query result
     cache: "passive" use is reading, "active" use is writing.
