Xcontent filter: Add map and builder filter benchmark (#81575)

I add the map and builder in the `FilterContentBenchmark`.  The result show that parser performance is much better than map and builder. Later my colleague and I will commit some PR, that It will replace from map and builder to parser.

In wildcard case, map filter is so slow:

```
Benchmark                                                  (fieldCount)  (inclusive)         (type)  Mode  Cnt         Score   Error  Units
FilterContentBenchmark.filterWithBuilder              10_wildcard_field         true  cluster_stats  avgt    2    229729.345          ns/op
FilterContentBenchmark.filterWithMap                  10_wildcard_field         true  cluster_stats  avgt    2  29668878.146          ns/op
FilterContentBenchmark.filterWithNewParserConfig      10_wildcard_field         true  cluster_stats  avgt    2    237100.911          ns/op

```

and parse filter has a little improvement with builder filter:
```

```

Here is the full benchmark result:
