[SPARK-31163][SQL] TruncateTableCommand with acl/permission should ha…

…ndle non-existed path

### What changes were proposed in this pull request?

This fix #26956
Wrap try-catch on `fs.getFileStatus(path)` within acl/permission in case of the path doesn't exist.

### Why are the changes needed?

`truncate table` may fail to re-create path in case of interruption or something else. As a result, next time we `truncate table` on the same table with acl/permission, it will fail due to `FileNotFoundException`. And it also brings behavior change compares to previous Spark version, which could still `truncate table` successfully even if the path doesn't exist.

### Does this PR introduce any user-facing change?

No.

### How was this patch tested?

Added UT.

Closes #27923 from Ngone51/fix_truncate.
