Distance measures for dense and sparse vectors (#37947) 
* Distance measures for dense and sparse vectors

Introduce painless functions of
cosineSimilarity and dotProduct distance
measures for dense and sparse vector fields.

```js
{
  "query": {
    "script_score": {
      "query": {
        "match_all": {}
      },
      "script": {
        "source": "cosineSimilarity(params.queryVector, doc['my_dense_vector'].value)",
        "params": {
          "queryVector": [4, 3.4, -1.2]
        }
      }
    }
  }
}
```

```js
{
  "query": {
    "script_score": {
      "query": {
        "match_all": {}
      },
      "script": {
        "source": "cosineSimilaritySparse(params.queryVector, doc['my_sparse_vector'].value)",
        "params": {
          "queryVector": {"2": -0.5, "10" : 111.3, "50": -13.0, "113": 14.8, "4545": -156.0}
        }
      }
    }
  }
}
```
