Add tracing to detect and build phases

[joshwlewis]

This wraps both build and detect with tracing, which results in.jsonl tracing files compatible with OpenTelemetry File Export. This will grant tracing information for all libcnb.rs based buildpacks.

It's setup such that any build or detect errors are tracked as such with events and statuses.

detect is also instrumented with detect-pass or detect-fail events, so it should be clear if a detect phase errored, failed, or passed.

Additionally, this adds metadata from the buildpack descriptor (buildpack name, version, api version) to each span.

Closing in favor of #723.
