Upgrade PyO3 from 0.26 to 0.27

Summary:
X-link: https://github.com/mslsrc/prod_inference/pull/5794

X-link: meta-pytorch/monarch#4543

Upgrade PyO3 to 0.27 and fix upgrade-time API breakages:
  - FromPyObject trait shape changed:
      - FromPyObject<'py> / extract_bound(&Bound<'py, PyAny>)
      - becomes FromPyObject<'a, 'py> with type Error and extract(Borrowed<'a, 'py, PyAny>)
  - extract() error typing is stricter:
      - extraction no longer always type-infers as PyErr cleanly in nested PyResult contexts.
      - Stack adds explicit closure return types and .map_err(Into::into) where needed.
  - Downcast APIs are replaced/deprecated:
      - downcast, downcast_bound, downcast_into, downcast_unchecked, DowncastError become cast, cast_bound, cast_into, cast_unchecked, CastError
  - PyCapsule pointer access changed:
      - old code used reference() or raw pointer() plus manual checks.
      - stack moves callsites toward pointer_checked(Some(c"...")), is_valid_checked, and CStr capsule names.

Also aligns required crates with pins and overlays:
   - bumps pyo3, pyo3-async-runtimes, pyo3-build-config, pythonize, and numpy to 0.27.
   - updates pyo3-python-tracing-subscriber to a compatible rev.
   - pins/patches Arrow crates to the git rev with arrow-pyarrow PyO3 0.27 support
   - adds a pyo3-build-config 0.27 overlay/fixup so the vendored crate works with our disabled-buildscript/cross-compile setup.
