Summary: Adds pcre2 to handle the negative lookbehinds in HuggingFace tokenizers. Performance stays about the same from test runs [before](https://github.com/pytorch-labs/tokenizers/actions/runs/14480863330/job/40617329721#step:14:758) (run on last commit on main) and [after](https://github.com/pytorch-labs/tokenizers/actions/runs/14526152504/job/40757962551#step:14:901) (this pr). Tokenizer library size (from `ls -lh build/libtokenizers.a`): `13M` (on main) -> `15M`. This most likely comes from adding the `pcre2` lib. 🧱 Stack: - [ ] #45 - [ ] #48 - [ ] #49 - [x] #50 Pull Request resolved: #50 Differential Revision: D73295314 Pulled By: jackzhxng
