Shutdown hooks cannot be modified during shutdown thrown during plugin intialization

### Backend

VL (Velox)

### Bug description

[Expected behavior] and [actual behavior].

We have seen cases where Spark shuts down due to some exception while Gluten plugin is being initialized, Gluten plugin tries to register shutdown hooks for cleaning up temporary directories. However, adding new shutdown hooks once the shutdown sequence has started is not allowed leading to an IllegalStateException and preventing graceful shutdown.

### Gluten version

Gluten-1.3

### Spark version

Spark-3.5.x

### Spark configurations

_No response_

### System information

_No response_

### Relevant logs

```

Start with SparkDirectoryUtil.scala and SparkShutdownManagerUtil.scala, following the stack trace from VeloxListenerApi.onDriverStart in the Gluten plugin initialization path. Reproduce the shutdown-time initialization failure and verify that cleanup registration no longer throws IllegalStateException, allowing graceful shutdown.
