Review gaps between ClientCore serialization support and azure-core's #50930

ClientCore removes the Jackson Databind backstop for serialization that azure-core had. Review current azure-core-based SDKs to determine which gaps, if any, exist with what the SDK needs and ClientCore supports. Determine if any generalized serialization interfaces need to be added to support ClientCore or if there needs to be updates to the internal serialization provider ClientCore has to close the gaps.
