Description

The methods hasBodyParameter, hasFormParameter, getConsumesInfo, getProducesInfo, addOneOfInterfaceModel, getOneOfAnyOfDescendants and discriminatorFound doesn't need to have an OpenAPI object as a parameter since the DefaultCodegen class already has it as an instance attribute and its its always required.

Also, removing the static property from getConsumesInfo and getProducesInfo facilitates override them.

Research direction

Start by reading the DefaultCodegen class and locating hasBodyParameter, hasFormParameter, getConsumesInfo, getProducesInfo, addOneOfInterfaceModel, getOneOfAnyOfDescendants, and discriminatorFound. Then trace their callers and overrides to identify all OpenAPI arguments and static declarations that must change. Done means the methods use the existing instance attribute and overrides remain possible without the static restriction.
