    [SPARK-23264][SQL] Support interval values without INTERVAL clauses

    ## What changes were proposed in this pull request?
    This pr updated parsing rules in `SqlBase.g4` to support a SQL query below;
    ```
    SELECT CAST('2017-08-04' AS DATE) + 1 days;
    ```
    The current master cannot parse it though, other dbms-like systems support the syntax
(e.g., hive and mysql). Also, the syntax is frequently used in the official TPC-DS queries.
    
    ## How was this patch tested?
    Added tests in `SQLQuerySuite`.
