Query Refactoring: validate GeoShapeQueryBuilder strategy and relation parameter

Before the refactoring we didn't check any invalid settings for strategy and relation
in the GeoShapeQueryBuilder. However, using SpatialStrategy.TERM and ShapeRelation.INTERSECTS
together is invalid and we tried to protect against that in the validate() method.

This PR moves these checks to setter for strategy and relation and adds tests for the new
behaviour.

Relates to #10217
