Overview of V2 `PrimitiveResult` and associated result objects

URL, if applicable

Add a new section to https://docs.quantum.ibm.com/run/visualize-results to go over extracting results.

Add a new section to https://docs.quantum.ibm.com/run/advanced-runtime-options to go over what data is returned in the DataBin for the corresponding runtime options.

Describe the new content you are requesting.

The result data returned by the Estimator primitive once a job has completed contains a variety of data depending on the error mitigation options. For example, when using ZNE, the PubResultand PrimitiveResult objects returned possess extrapolated expectation values, noise factors used, metadata about the learned noise model, among other things.

The documentation on how this is organized is fairly sparse, including in the API documentation. This (I assume) is partly due to the fact that the underlying DataBin objects possess different values depending on the runtime options specified for the job(s). I think we should add the following

[ ] An explanation of the relationship between PrimitiveResult, PubResult, and the DataBin objects
[ ] A table or something similar depicting the corresponding (meta)data that gets included in the DataBin for the various runtime options available.

If this new content request is accepted, do you want to write the content?

I will write a draft of the proposed content
