    [FLINK-6697] [table] Add support for window.rowtime to batch Table API.

    ## What is the purpose of the change
    
    This PR adds support for the `windowAlias.rowtime` property to the batch Table API. The `rowtime` expression is already supported by the streaming Table API. 
    
    This PR improves the unification of batch and streaming Table API queries.
    
    ## Brief change log
    
    - adjust the validation and return type of the `RowtimeAttribute` expression
    - pass rowtime index to DataSet window operators
    - adjust `TimeWindowPropertyCollector` to set rowtime attribute in batch windows
    - extend existing tests to check the new window property
    
    ## Verifying this change
    
    - existing tests in `GroupWindowITCase` were extended to check the `rowtime` window property.
