[Java] Implement "ArrowBufReadChannel" abstraction and alternate MessageSerializer that uses this

The current MessageSerializer implementation is wasteful when used to read an IPC payload that is already in-memory in an `ArrowBuf`. In particular, reads out of a `ReadChannel` require memory allocation

- https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/ipc/message/MessageSerializer.java#L569

- https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/ipc/message/MessageSerializer.java#L290

In C++, we have abstracted memory allocation out of the IPC read path so that zero-copy is possible. I suggest that a similar mechanism can be developed for Java to improve deserialization performance for in-memory messages. The new interface would return `ArrowBuf` when performing reads, which could be zero-copy when possible, but when not the current strategy of allocate-copy could be used

Leggere java/vector/src/main/java/org/apache/arrow/vector/ipc/message/MessageSerializer.java alle righe referenziate 569 e 290 per comprendere l’attuale percorso di allocazione di ReadChannel. Esaminare l’astrazione ArrowBufReadChannel proposta e il MessageSerializer alternativo, con letture zero-copy per i payload ArrowBuf in memoria e un fallback di allocazione-copia come criteri di completamento.
