Add fields to `ListBatchOperations` and `DescribeBatchOperation` API responses

Is your feature request related to a problem? Please describe.
After building pages in the Web UI to visualize Batch Operations, I observed some improvements that could be made to the ListBatchOperations and DescribeBatchOperation APIs. Specifically, when listing Batch Operations, only 4 fields are returned. This limits users in trying to differentiate their Batch Operations when listed in a tabular format, as the only uniquely identifiable field that is returned is the Job ID. Additionally, there is no way for a user to associate the Batch Operation back to a list of Workflows that were affected by the Batch Operation.

Describe the solution you'd like
I'd like to suggest that the following additions are made:

• operation type is added to the ListBatchOperations response.
• the visibility query (or the list of workflow executions when a batch operation was created with the executions parameter) is returned on the DescribeBatchOperation response.

Describe alternatives you've considered

Additional context
Add any other context or screenshots about the feature request here.
Currently the information we receive in the ListBatchOperations API response is quite limited and does not provide a lot of meaningful context to the user.

Start by locating the API definitions and server implementations for ListBatchOperations and DescribeBatchOperation. Trace the existing response fields and request inputs, then confirm that operation type and the visibility query or executions data are exposed as requested.
