refactor(lex_parser): replace core_pos_* functions with scc_pos_* equivalents

Update all position tracking calls in lex_parser.c to use the scc_pos_* function family (scc_pos_next, scc_pos_next_line) instead of the deprecated core_pos_* variants. This ensures consistency with the scc naming convention and prepares for future removal of the old core functions.
