ice: parse and init various DDP parser sections

Parse the following DDP sections:
 - ICE_SID_RXPARSER_IMEM into an array of struct ice_imem_item
 - ICE_SID_RXPARSER_METADATA_INIT into an array of struct ice_metainit_item
 - ICE_SID_RXPARSER_CAM or ICE_SID_RXPARSER_PG_SPILL into an array of
   struct ice_pg_cam_item
 - ICE_SID_RXPARSER_NOMATCH_CAM or ICE_SID_RXPARSER_NOMATCH_SPILL into an
   array of struct ice_pg_nm_cam_item
 - ICE_SID_RXPARSER_CAM into an array of ice_bst_tcam_item
 - ICE_SID_LBL_RXPARSER_TMEM into an array of ice_lbl_item
 - ICE_SID_RXPARSER_MARKER_PTYPE into an array of ice_ptype_mk_tcam_item
 - ICE_SID_RXPARSER_MARKER_GRP into an array of ice_mk_grp_item
 - ICE_SID_RXPARSER_PROTO_GRP into an array of ice_proto_grp_item
 - ICE_SID_RXPARSER_FLAG_REDIR into an array of ice_flg_rd_item
 - ICE_SID_XLT_KEY_BUILDER_SW, ICE_SID_XLT_KEY_BUILDER_ACL,
   ICE_SID_XLT_KEY_BUILDER_FD and ICE_SID_XLT_KEY_BUILDER_RSS into
   struct ice_xlt_kb
