GeoDistanceRangeQueryBuilder to not change its state when calling toQuery

The geoPoint gets normalized while calling toQuery. That should happen on a copy of the point though, the state of the request should never change as part of toQuery execution. Also updated corresponding test to support point normalization.

Closes #13984
