Evaluate if refactor of CreateMutation.Build() to accept RuntimeConfig object is beneficial

[severussundar]

PR #2116 introduces a new parameter called isMultipleCreateOperationEnabled to CreateMutationBuilder.Build() method.

isMultipleCreateOperationEnabled can be computed using RuntimeConfig.IsMultipleCreateOperationEnabled().
CreateMutationBuilder.Build() method accepts another parameter called entities of type RuntimeEntities. This can be got from RuntimeConfig.RuntimeEntities

Evaulate if it is beneficial to refactor CreateMutationBuilder.Build() method to accept RuntimeConfig object instead of two parameters separately.

Upon initial analysis, IMHO, this refactor offers little benefit as RuntimeEntities and IsMultipleCreate are the fields relevant/needed for schema generation. We don't necessarily need the entire RuntimeConfig object.

Open to suggestions on other lines of thought.
