This allows you to specify multiple logging scopes, both in API and the CLI.
e.g for the CLI.
```bash
$ wazero run --hostlogging=crypto --hostlogging=filesystem --mount=.:/:ro cat.wasm
```
e.g. for Go
```go
loggingCtx := context.WithValue(testCtx, experimental.FunctionListenerFactoryKey{},
logging.NewHostLoggingListenerFactory(&log, logging.LogScopeCrypto|logging.LogScopeFilesystem))
```
