## [Security Solution] Fixes sorting issues related to unmapped fields

This PR fixes the following issues related to sorting unmapped fields in timelines and the events / alerts tables:

- <#129603>
- <#123912>
- <#131625>

The `unmapped_type` property [addition](https://github.com/elastic/kibana/pull/87241/files#diff-52fd5870dcd5f783f9fc8ac3a18a8674d83ac6136e09fe0e0bcae30427d61c3fR55) to the `sort` parameter of requests was using the `type` field metadata from `BrowserFields`, but the `type` metadata (for some fields) contains the value `string`, which is not a [valid field data type](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-types.html).

The fix for the issues above:

- Populates the `sort` property of requests with values from the `esTypes` `BrowserFields` metadata (instead of `type`)
  - The `esTypes` metadata may specify more than one field value type. When `esTypes` contains more than one type, and `keyword` is one of the types, the `sort` property of the request will prefer `keyword` over other the other types
- When the field metadata has an empty `esTypes` collection, the `sort` property of the request will default to using `"unmapped_type": "keyword"`
- The field type displayed in tooltips when hovering over columns in a timeline now displays values from `esTypes` instead of `type`

### Desk testing

To reproduce issue <#129603> and to verify the fix:

1) Open Kibana `Dev tools`

2) Execute the following query to delete any exiting `logs-ti_test` index:

```
DELETE logs-ti_test
```

3) Execute the following query to create an index named `logs-ti_test`, which has the following properities:

- Dynamic mappings are disabled via `"dynamic": false`
- It does NOT contain a mapping for `event.action` (we will sort by this field in later steps)
- It contains a mapping for the non-ECS `testing` field

```
PUT logs-ti_test
{
  "mappings": {
    "dynamic": false,
    "properties": {
      "@timestamp": {
        "type": "date"
      },
      "event": {
        "properties": {
          "category": {
            "type": "keyword"
          },
          "dataset": {
            "type": "keyword"
          },
          "kind": {
            "type": "keyword"
          },
          "type": {
            "type": "keyword"
          }
        }
      },
      "host": {
        "properties": {
          "name": {
            "type": "keyword"
          }
        }
      },
      "testing": {
        "type": "keyword",
        "ignore_above": 1024
      },
      "threat": {
        "properties": {
          "indicator": {
            "properties": {
              "file": {
                "properties": {
                  "hash": {
                    "properties": {
                      "md5": {
                        "type": "keyword"
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}
```

4) Execute the following query to add a new document to the `logs-ti_test` index, and note that:

- It does NOT contain a `event.action` field
- It contains a value for the non-ECS `testing` field

```
POST logs-ti_test/_doc/
{
  "@timestamp": "2022-05-12T00:00:14.725Z",
  "host": {
    "name": "foozle"
  },
  "threat": {
    "indicator": {
      "file": {
        "hash": {
          "md5": "a4f87cbcd2a4241da77b6bf0c5d9e8553fec991f"
        }
      }
    }
  },
  "event": {
    "kind": "enrichment",
    "type": "indicator",
    "dataset": "ti_*",
    "category": "threat"
  },
  "testing": "simulated threat intel data"
}
```

5) Navigate to the Security > Hosts page

6) Select `Last 1 year` from the date picker

7) Click the `Events` tab

8) Enter the following KQL query in the search bar at the top of the page:

```
host.name: foozle
```

9) Hover over the `foozle` entry in the `host.name` column in the Events table, and click the `Add to timeline investigation` cell action

10) Open the timeline

11) Hover over the `event.action` field

**Expected result**

- The tooltip displays  type `keyword` for the `event.action` field

**Actual result**

- The tooltip displays type `string` for the `event.action` field

12) Click the `event.action` column to add a secondary sort

**Expected result**

- The table is sorted by `@timestamp` and `event.action`
- The table contents are (still) visible

**Actual result**

- The table is sorted by `@timestamp` and `event.action`
- The contents of the table are now empty

13) Click the timeline's `Inspect` button

14) In the `Inspect Timeline` dialog, click the `Request` tab

15) Scroll down to the `sort` property of the request

**Expected result**

- The `event.action` field contains a `"unmapped_type": "keyword"` property, per the example below:

```json
  "sort": [
    {
      "@timestamp": {
        "order": "desc",
        "unmapped_type": "date"
      }
    },
    {
      "event.action": {
        "order": "desc",
        "unmapped_type": "keyword"
      }
    }
  ],
  ```

**Actual result**

- The request's `event.action` field contains a `"unmapped_type": "string"` property, per the example below:

```json
  "sort": [
    {
      "@timestamp": {
        "order": "desc",
        "unmapped_type": "number"
      }
    },
    {
      "event.action": {
        "order": "desc",
        "unmapped_type": "string"
      }
    }
  ],
  ```

16) In the `Inspect Timeline` dialog, click the `Response` tab

**Expected result**

- The response contains `0` `failed` shards / no failures

**Actual result**

- The response contains failures for the `logs-ti_test` index, with the following reason:

```
"reason": "No mapper found for type [string]"
```

per the example below:

```json
{
  "took": 1,
  "timed_out": false,
  "_shards": {
    "total": 4,
    "successful": 3,
    "skipped": 0,
    "failed": 1,
    "failures": [
      {
        "shard": 0,
        "index": "logs-ti_test",
        "node": "NCRcGeDqSlKQiuPWVFvMEg",
        "reason": {
          "type": "illegal_argument_exception",
          "reason": "No mapper found for type [string]"
        }
      }
    ]
  },
```
