Mapper: Throw exception if null_value is set to null

The mapping parser should throw an exception if "null_value" is set to `null`. Fixes #7273 ```bash PUT /foo { "mappings": { "bar": { "properties": { "exception": { "null_value": null, "type": "integer" } } } } } ``` ``` { "error": "MapperParsingException[mapping [bar]]; nested: MapperParsingException[Property [null_value] cannot be null.]; ", "status": 400 } ```
