[SPARK-46480][CORE][SQL] Fix NPE when table cache task attempt
### What changes were proposed in this pull request?
This pr adds a check: we only mark the cached partition is materialized if
the task is not failed and not interrupted. And adds a new method `isFailed` in
`TaskContext`.
### Why are the changes needed?
Before this pr, when do cache, task failure can cause NPE in other tasks
```
