Add Python 3.12 to wheel build matrix (#9)

## Summary
- Adds Python 3.12 (3.12.8) to the `PYTHON_VERSIONS` default in
`deploy/build_wheels.sh`
- Adds compile-from-source block for 3.12, following the same pattern as
3.10/3.11

## Test plan
- [ ] Kick off Jenkins build with this branch to verify 3.12 wheels
build for both x86_64 and aarch64
