Like OpenSearch, add array support to k-NN vector field type.

For Example - Let us assume testindex is a k-NN index and my_vector1 is a field of knn_vector field type having dimension as 3. Here, we are trying to ingest a document into that index using array of vectors (array of arrays).

PUT testindex/_doc/1
{
  "my_vector1": [[1, 2, 3], [4,5,6], [7,8,9]] 
}

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.

Closing this issue as we are not supporting this feature right now due to underlying limitations and this will not be included for v2.7.0
