openlineage-sql: add build-openlineage-sql.yml for riscv64 wheels

[luhenry]

• Package: openlineage-sql
• Version: 1.53.0
• Source: https://github.com/OpenLineage/OpenLineage (monorepo, integration/sql)
• Docs: https://github.com/OpenLineage/OpenLineage

Compiles the OpenLineage SQL lineage parser, a pyo3/maturin extension over the sqlparser crate, into an abi3 wheel. Upstream publishes no riscv64 wheel.

Mirrors upstream's build-integration-sql-python CircleCI job.

Differs from upstream

• Stages LICENSE/NOTICE.txt into iface-py/ - maturin globs licence files next to pyproject.toml, which sits below the repo root.
• Runs the impl crate's cargo test in its own job - upstream bundles it into the same job as the wheel build.

Matrix: cp310-abi3 (built once) + cp314t - pyo3's abi3-py310 feature is unconditional in Cargo.toml.

Testing

• cargo test --no-default-features -p openlineage_sql, mirroring upstream's run_tests: true step.
• Wheel-level: upstream's own tests/python/test_small.py via pytest, plus a .so and licence-file check.

License: OK

Built on cp312 equivalent (aarch64, local); 148 impl-crate tests passed, 3 ignored, and 1 pytest passed.
