Emit a message on `cache clean` and `prune` when lock is held (#16138) 

Closes https://github.com/astral-sh/uv/issues/16112

```
❯ cargo run -q cache clean
Cache is currently in-use, waiting for other uv processes to finish (use `--force` to override)
```

Otherwise, `-v` is required to see we're waiting on a lock.

I'd rather do this than elevate the exclusive lock log message to
something more verbose because this allows us to use a more specific
message as appropriate for the situation. We also previously reduced the
verbosity of arbitrary locks, e.g., see
