build: remove ZetaSQL and update dependencies for Python 3.12 support

This commit modernizes the build environment and strips out dependencies
that block compilation on Python 3.12.

Specific changes include:
* Strip ZetaSQL: Removed zetasql and six_archive from `WORKSPACE`.
  Deleted `sql_util` and `statistics_sql` C++ submodules and their
  pybind11 hooks, as ZetaSQL compilation fails in this environment.
* Modernize PyArrow: Relaxed pyarrow constraints to `>=14,<22` for
  Python >= 3.11 to avoid downloading and building legacy Arrow 10
  source code (which lacks modern setuptools/pkg_resources support).
* Bump Dependencies: Updated tensorflow constraint to `>=2.16,<2.18`
  and explicitly added `dill>=0.4.1` to fix Apache Beam serialization
  crashes during local testing.
* Cleanup Build Macros: Removed legacy Python 2 pybind11 initialization
  symbols (`init%s`) from `build_macros.bzl`, keeping only `PyInit_%s`.

There were some conflicts, which I've resolved, am open to any changes maintainers want to suggest/make. My build environment is likely different than the environment which produces the whls, and would like to understand the build/test process better.
