feat(telemetry): Integrate tools_telemetry (#612)

This patch integrates
[tools_telemetry](https://github.com/aspect-build/tools_telemetry) into
`rules_py`. Depending on `rules_py` will register a dependency into the
telemetry system and produce a usage report when external repositories
are invalidated.

### Changes are visible to end-users: yes

- Suggested release notes appear below: yes

`aspect_tools_telemetry` is now used for coarse grained usage tracking.

### Test plan

N/A.
