[I] [Bug] disable streaming read of ReadOptimizedTable which has primary-key. [paimon]

liming30 opened a new issue, #4191:
URL: https://github.com/apache/paimon/issues/4191

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
   
   
   ### Paimon version
   
   paimon-0.9 snapshot
   
   ### Compute Engine
   
   flink-1.17.2
   
   ### Minimal reproduce step
   
   Stream a `ReadOptimizedTable`, which contains the primary key.
   
   ### What doesn't meet your expectations?
   
   `ReadOptimizedTable` with primary key should only provide batch read. In streaming mode, the semantics of incremental data are strange.  For example, if `changelog-producer` is set to `INPUT`, we will not be able to obtain incremental data because we only obtain the top-level files. At the same time, `SystemTable` should only provide `insert-only` data, which means that `ReadOptimizedTable` cannot provide retract messages.
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [X] I'm willing to submit a PR!
