[report_result] Add testcase error detection and reporting

Previously, report_result.yml only checked for testcase failures but
ignored errors in the JUnit XML output. This meant that tests could
error out without causing the CI job to fail.

This change adds:
- Extraction of 'errors' count from XML testsuites
- Failure task that triggers when errors > 0

This ensures both failures and errors in testcases are properly
reported and cause the CI job to fail as expected.
