[I] [CORE][VL] V2 columnar write [incubator-gluten]

["zhztheplayer (via GitHub)" <gi...@apache.org>]

zhztheplayer opened a new issue, #9896:
URL: https://github.com/apache/incubator-gluten/issues/9896

   ### Description
   
   The topic is to enable DSV2 write in Gluten, also in preparation for Iceberg support.
   
   This will involve:
   
   1. Have a V2 columnar write API
   2. Test: Add columnar version of `InMemoryTableCatalog` (e.g., `ColumnarInMemoryTableCatalog`) that fits into V2 columnar write API, but not necessarily do columnar processing internally (could reuse `InMemoryTableCatalog`'s row-based storage after the data passes through the columnar API) 
   3. Enable `DataFrameWriterV2Suite` 
   
   ### Gluten version
   
   None
