fix(wpss_remoteproc): ensure .res file is created on fail_and_exit paths

- Replaced usage of `fail_and_exit` with explicit logging and .res file creation
- Ensures that all failure exit paths write the expected result file (e.g., wpss_remoteproc.res)
- Fixes issue where send-to-lava.sh reports missing result file due to early script exit without writing status
- Also avoids silent test failures being marked incomplete by CI infrastructure
