Add data loader overloads to MicrosoftDI resolver builders

[Shane32]

Fixes #3510

• Cannot implicitly convert type IDataLoaderResult<T> to T #3510

[Shane32]

Questions:

• Should this extension method exist only in the DataLoader library? Or only the MicrosoftDI library? Or perhaps the resolver builder feature of the MicrosoftDI library should have additional overloads for ResolveAsync that accept data loaders, similar to the added overloads to ResolveAsync ?

I think adding overrides to MicrosoftDI is cleaner. The ReturnsDataLoader is another level of complexity that you must know to define the field. If I were going to convert my existing code to use ResolverBuilder, I'd expect only to add .Resolve().WithService<T>(). But instead, I need to start looking around to find out I also need to add ReturnsDataLoader. This will also complicate implementation of this analyzer #3781
