[Java] VarBinaryWriter should support writing from `byte[]` or `ByteBuffer`

[lidavidm]

Describe the enhancement requested

The writer API only supports writing from ArrowBuf. So if you don't already have an ArrowBuf, you have to make a new allocation and copy the data over, only for the writer to copy the data from your new allocation into the vector. VarBinaryWriter should just also support these common types for bytestrings and eliminate an unnecessary copy. (VarBinaryVector already has overloads for both.)
