[SPARK-49937][INFRA] Ban call the method SparkThrowable#getErrorClass

### What changes were proposed in this pull request?
The pr aims to ban call the method `SparkThrowable#getErrorClass`.

### Why are the changes needed?
After PR #48196, `SparkThrowable#getErrorClass` has been marked as `Deprecated`. In order to prevent future developers from calling `SparkThrowable#getErrorClass` again, which may require continuous fix and migration, calling `SparkThrowable#getErrorClass` is strictly prohibited as it will fail at the compilation level.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
- Pass GA.
- Manually test.

### Was this patch authored or co-authored using generative AI tooling?
No.

Closes #48426 from panbingkun/SPARK-49937.
