feat(lex_parser, pprocessor): replace consume with next and remove stream resets

- Replace `scc_probe_stream_consume` with `scc_probe_stream_next` for consistent stream advancement
- Remove redundant `scc_probe_stream_reset` calls before peeking, as `next` and `peek` handle state
- Update `scc_cstring_new` to `scc_cstring_create` and `scc_pos_init` to `scc_pos_create` for naming consistency
- Change `scc_pp_macro_get` parameter to `const scc_cstring_t*` for better const-correctness
- Improves code clarity and maintains proper stream position tracking
