[Java] SplitAndTransfer throws for (0,0) if vector empty

[asfimport]

I've hit a bug where splitAndTransfer on vectors throws if the vector is completely empty and the offset buffer is empty.

An easy repro is:

        BufferAllocator allocator = new RootAllocator(Long.MAX_VALUE);
        ListVector listVector = ListVector.empty("listVector", allocator);
        listVector.getTransferPair(listVector.getAllocator()).splitAndTransfer(0, 0);

This results in the following stacktrace:

java.lang.IndexOutOfBoundsException: index: 0, length: 4 (expected: range(0, 0))
	at io.netty.buffer.ArrowBuf.checkIndexD(ArrowBuf.java:335)
	at io.netty.buffer.ArrowBuf.chk(ArrowBuf.java:322)
	at io.netty.buffer.ArrowBuf.getInt(ArrowBuf.java:441)
	at org.apache.arrow.vector.complex.ListVector$TransferImpl.splitAndTransfer(ListVector.java:484)

In production we hit this when calling VectorSchemaRoot.slice. The schema root contains a ListVector with a VarCharVector value vector. The list vector isn't empty, but all the strings in the var char vector are. splitAndTransfer on the list vector works, but then when underlying var char vector is split we get the same exception:

The problem seems to affect BaseLargeVariableWidthVector, BaseVariableWidthVector, ListVector and MapVector.
