URL: https://github.com/apache/paimon/pull/4891

   <!-- Please specify the module before the PR name: [core] ... or [flink] ... 
-->
   
   ### Purpose
   Due to the introduction of an external path[1], we are unable to use the 
warehouse's `FileIO` to read and write files. So we introduced `HybirdFileIO`, 
which allows us to choose the appropriate fileio based on the prefix scheme of 
the path.
   
   This job is a part of this job[2]

   ### Tests
   
   Add HybridFileIOTest.java UT
   
   ### API and Format
   
   no change
   
   ### Documentation
   
   Because the external path of the file is on the table options. So we don't 
know the specific file write path from the options in the catalog. So we don't 
know the underlying write path is an object store or not.
   So we need to modify the `write-buffer-spillable` parameter. Make it default 
to false
