Fix losing batch call errors for individual requests

[amit-momin]

Issue

• If an error occurs for an individual request during a batch call, it is populated in the BatchElem.Error field. Documentation
• The current code loses access to these request specific errors
• The original BatchElem is not populated with the error because the existing code casts the requests into an array of any in the multinode code then back to BatchElem in the rpc client code.

Solution

• Introduce a new generic to pass the BatchElem type to the multinode and rpc client interfaces
• Update the BatchCallContext and BatchCallContextAll methods to directly take the BatchElem as a parameter
• Remove code from multinode and rpc client that cast the requests from BatchElem to any then back allowing the original request passed in to be populated with individual errors to be used by the caller

I see that you haven't updated any CHANGELOG files. Would it make sense to do so?
