Phase 5: implement all 14 remaining TPC-DS dimension tables

Adds support for all 24 TPC-DS tables to tpcds_benchmark:
call_center, catalog_page, web_page, web_site, warehouse, ship_mode,
household_demographics, customer_demographics, customer_address,
income_band, reason, time_dim, promotion, store.

Key changes:
- tpcds_dsdgen.h: fix ds_addr_t (add missing plus4 field); add structs
  and TPCDS_* constants for all 14 new tables
- dsdgen_wrapper.hpp/.cpp: TPCDS_SIMPLE_GENERATE macro + 14 new generators
- dsdgen_converter.cpp: append_*_to_builders + dispatcher for 14 tables;
  append_addr_fields() helper for ds_addr_t (street/city/state/zip/etc.)
- tpcds_main.cpp: parse_table() + generation dispatch for all 24 tables
