Pass arrays as single positional parameter for prepared-statement caching

Instead of expanding arrays into individual parameters (e.g. IN [$1, $2]),
pass the whole array as one parameter (e.g. IN $1). This keeps the query
string stable regardless of array length, enabling Couchbase to cache the
prepared statement for IN queries.
