Summary: [C++] Support dictionary memos when reading/writing record batches using cuda IPC
Key: ARROW-8927
URL: https://issues.apache.org/jira/browse/ARROW-8927
Project: Apache Arrow
Issue Type: Improvement
Reporter: Alex Baden
Currently, the cuda IPC calls for `ReadRecordBatch` do not accept a dictionary memo as a parameter, building an empty memo before calling `ipc::ReadRecordBatch`. As such, adding a test which duplicates `TestCudaArrowIpc, BasicWriteRead` but calls `MakeDictionary` to create the record batch fails because the dictionaries for the original record batch are not found. The cuda IPC calls should be modified to take a dictionary memo, just like the standard IPC API.
