Subject: [PATCH 3/7] build and test Linux-ARM wheels

- `.github/workflows/tests.yml`:
  - `build_binpy_wheels`:
    - Activate QEMU on Linux so that `aarch64` wheels can be built
    - Removed `${CIBW_ARCHS_LINUX}` to use `pyproject.toml` values
  - `test_binpy_wheels`:
    Added corresponding `ubuntu-24.04-arm` steps for all `ubuntu-latest`
    (i.e. x86) steps
- `pyproject.toml`:
  Added `[tool.cibuildwheel.linux]` section in parallel to `macos` and
  `windows`
