Description
### Describe the enhancement requested
Once the `Utf8View` and `BinaryView` have been introduced, we have added a new attribute to the `RecordBatch` [spec](https://github.com/apache/arrow/blob/main/format/Message.fbs#L117). Once this change is integrated, we need to update the existing interfaces which uses this and related modules which use those interfaces. To introduce this change, it would be better to include this by introducing them component wise so that it can be tested in a streamlined manner.
Following are list of modules and their classes which are related with the changes done to update the `RecordBatch` specification.
### Vector
- [ ] `JsonFileReader`
- [ ] `JsonFileWriter`
- [ ] `ArrowReader`
- [X] `TestValueVector`
- [X] `TestVarcharViewVector`
- [ ] `TestVectorUnloadLoad`
- [ ] `TestArrowReaderWriter`
- [ ] `TestRoundtrip`
- [ ] `TestJsonFile`
- [ ] `ArrowRecordBatchBenchmarks`
- [ ] `MessageSerializerTest`
- [ ] `ArrowDictionaryBatch`
- [ ] `ArrowStreamReader`
- [ ] `TestValidateVector`
### Performance
- [ ] `VectorLoaderBenchmark`
- [ ] `VectorUnloaderBenchmarks`
### C
- [ ] `RoundtripTest`
- [ ] `StreamTest`
### Dataset
- [ ] `TestDataset`
- [ ] `TestFileSystemDataset`
- [ ] `ArrowScannerReader`
- [ ] `NativeScanner`
### Flight
- [ ] `TestFlightClient`
- [ ] `TestDoExchange`
- [ ] `IntegrationTestClient`
- [ ] `FlightStream`
- [ ] `IntegrationProducer`
- [ ] `ExpirationTimeDoGetScenario`
- [ ] `VectorSchemaRootTransformerTest`
- [ ] `FlightSQLExample`
- [ ] `TestBasicOperation`
### Compression
- [ ] `TestCompressionCodec`
### Gandiva
- [ ] `ProjectorTest`
- [ ] `ProjectorDecimalTest`
- [ ] `FilterTest`
- [ ] `FilterProjectTest`
- [ ] `BaseEvaluatorTest`
### Component(s)

Contributor guide
Research direction
Start with the RecordBatch specification and the existing Java interfaces affected by variadicBufferCounts, then work component by component through the unchecked Vector, Performance, C, Dataset, Flight, Compression, and Gandiva classes. Use the checked TestValueVector and TestVarcharViewVector work as context. Done means the listed modules are updated consistently and their relevant tests pass.
