URL: https://github.com/apache/doris/pull/39638

   * Target 
   
   Fix the behavior of cast numeric as boolean.
   
   Unlike mysql, doris has real boolean type( 
https://doris.apache.org/docs/2.0/table-design/data-type/). The only possible 
values of a boolean type in doris should be 0 or 1. 
   
   Currently, the computation of type bool is replaced with UInt8, which means 
we could get values like 2,3,4 for boolean column.
   
   * Fix
   
   This pr fix the computation of cast numeric as boolean, and add some check 
when we do result serialization.
   We need more work in scanner
   
   * Future work
   
   Do value convert in scanner. To make sure we will only get 0/1 for bool 
column even though value in storage is others.
