logging: adds memory scope (#1076)

This allows you to specify the memory scope amongst existing logging scopes, both in API and the CLI.

e.g for the CLI.
```bash
$ wazero run --hostlogging=memory,filesystem --mount=.:/:ro cat.wasm
```

e.g. for Go
```go
loggingCtx := context.WithValue(testCtx, experimental.FunctionListenerFactoryKey{},
	logging.NewHostLoggingListenerFactory(&log, logging.LogScopeMemory|logging.LogScopeFilesystem))
```

This is helpful for emscripten and gojs which have memory reset
callbacks. This will be much more interesting once #1075 is implemented.
