Description
### Describe the enhancement requested
Analogous to https://github.com/apache/arrow-java/issues/1035 but for DictionaryBatch.
The Arrow IPC format supports Message level `custom_metadata`, see https://arrow.apache.org/docs/format/Columnar.html#custom-application-metadata and https://github.com/apache/arrow/blob/main/format/Message.fbs#L154
The DictionaryBatch in this implementation currently has no support for this field.
Contributor guide
Research direction
Compare the DictionaryBatch implementation with the analogous work in Apache Arrow issue 1035, and inspect the IPC Message.fbs definition for the message-level custom_metadata field. Done means DictionaryBatch supports that field consistently with the Arrow IPC format; verify the behavior with the repository's existing tests.
