apacheGH-40820: [Java] Adding Spotless to Adapter module (apache#42048)

### Rationale for this change

Adding code style and formatting options for Adapter module. 
- [X] Avro
- [x] JDBC
- [x] Orc

### What changes are included in this PR?

Code formatting spotless plugin has been added. 

### Are these changes tested?

Yes, but doesn't involve test cases, the plugin itself corrects. 

### Are there any user-facing changes?
* GitHub Issue: apache#40820
