apsw: add build-apsw.yml for riscv64 wheels (#1071)

* **Package**: `apsw`
* **Version**: `3.53.4.0`
* **Source**: https://github.com/rogerbinns/apsw
* **Docs**: https://rogerbinns.github.io/apsw/

CPython C extension wrapping SQLite, built against a downloaded matching SQLite amalgamation. Upstream publishes no riscv64 wheel.

Mirrors upstream's [`build-pypi.yml`](https://github.com/rogerbinns/apsw/blob/3.53.4.0/.github/workflows/build-pypi.yml) `binary` job.

**Differs from upstream**
- Only Linux (glibc) - upstream also builds macOS, Windows and pyodide.

**Testing**
- same as upstream

**License**: OK
