[SPARK-52645] Enable `ExitOnOutOfMemoryError` JVM option by default
### What changes were proposed in this pull request?
This Pr aims to enable `ExitOnOutOfMemoryError` JVM option by default.
### Why are the changes needed?
To help users identify the problematic situation as earlier as possible.
### Does this PR introduce _any_ user-facing change?
Yes, but OOM should not be ignored.
After this PR, the JVM will exit on the first `OutOfMemoryError` it
encounters, terminating the process with exit code 3.
### How was this patch tested?
Pass the CIs.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #266 from dongjoon-hyun/SPARK-52645.
