[I] [C++][Parquet] Unify normalize dictionary encoding handling [arrow]

mapleFU opened a new issue, #41818:
URL: https://github.com/apache/arrow/issues/41818

   ### Describe the enhancement requested
   
   This is mentioned here: https://github.com/apache/arrow/pull/40957#discussion_r1562703901
   
   There're some points:
   
   1. https://github.com/apache/arrow/blob/main/cpp/src/parquet/encoding.cc#L444-L445 . encoding is not passed in Encoder
   2. But shit, it's RLE in decoder 😅: https://github.com/apache/arrow/blob/main/cpp/src/parquet/encoding.cc#L1607 it will be detect and normalized in other place, like: 
   3. https://github.com/apache/arrow/blob/main/cpp/src/parquet/column_reader.cc#L876
   
   We'd better unifying them
   
   
   
   ### Component(s)
   
   C++, Parquet
