ice: Move support DDP code out of ice_flex_pipe.c

Currently, ice_flex_pipe.c includes the DDP loading functions and has grown large. Although flexible processing support code is related to DDP loading, these parts are distinct. Move the DDP loading functionality from ice_flex_pipe.c to a separate file.
