    ### Why is this PR needed?
    Spatial index feature optimization of CarbonData
   
    ### What changes were proposed in this PR?
   1. Update spatial index encoded algorithm, which can reduce the required properties of creating geo table
   2. Enhance geo query UDFs, support querying geo table with polygon list, polyline list, geoId range list. And add some geo transforming util UDFs.
   3. Load data (include LOAD and INSERT INTO) allows user to input spatial index, which column will still generated internally when user does not give.
   
       
    ### Does this PR introduce any user interface change?
    - No
   
    ### Is any new testcase added?
    - Yes
