clean up logging around on-demand downloads (#4030)

Browse Source 
- Remove repeated tenant & timeline from span
- Demote logging of the path to debug level
- Log completion at info level, in the same function where we log errors
- distinguish between layer file download success & on-demand download
succeeding as a whole in the log message wording
- Assert that the span contains a tenant id and a timeline id

fixes https://github.com/neondatabase/neon/issues/3945

Before:

```

After:

```
  INFO compaction_loop{tenant_id=$TENANT_ID}:compact_timeline{timeline=$TIMELINE_ID}:download_remote_layer{layer=000000000000000000000000000000000000-FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF__00000000020C8A71-00000000020CAF91}: layer file download finished
