    [fix][client] Fixes batch_size not checked in 
MessageId#fromByteArrayWithTopic (#18405)
    
    Fixes https://github.com/apache/pulsar/issues/18395
    
    ### Motivation
    
    The old version Pulsar clients might not set the `batch_size` field in a
    batched message id, it will cause `MessageId#fromByteArrayWithTopic`,
    which only checks the `batch_index` field, fail with
    IllegalStateException.
    
    ### Modifications
    
    Check if the `batch_size` field exists in `fromByteArrayWithTopic`. If
    it doesn't exist, create the `BatchMessageIdImpl` instance with the
    default batch size (0) and the acker (disabled).
    
    Move `MessageIdSerializationTest` to the `pulsar-client` module and add
    the `testBatchSizeNotSet` to verify the change works.
    
    (cherry picked from commit 8246e3bdd2173541b15dc1a26738bf59639949eb)
