Simon Willnauer 7513c6e4eb Remove QUERY_AND_FETCH search type (#22996)
`QUERY_AND_FETCH` has been treated as an internal optimization for 2 major
versions. This commit removes the search type and it's implementation details and
folds the optimization in the case of a single shard into the search controller such
that every search with a single shard (non DFS) will receive this optimization.
