SQS read IO requires deterministic coder for SQS message to work in batch mode mode.

    Description

      Currently the SQS read IO uses SerializableCoder.of(Message.class), which isn't deterministic. This may cause issues when used in batch mode (based on BoundedReadFromUnboundedSource). The mutation detector will throw in such case:
