[WIP] Add bailout support to test runner using AbortController

[Copilot]

Implementation Plan for Test Runner Bailout Feature

• Add --test-bail CLI option in src/node_options.cc
• Add bailout configuration parsing in lib/internal/test_runner/utils.js (parseCommandLine)
• Modify lib/internal/test_runner/test.js to abort parent test when first subtest fails (if bailout enabled)
• Add bailout propagation logic in processPendingSubtests method
• Create test fixtures for bailout functionality
• Add tests to validate bailout behavior
• Run existing test suite to ensure no regressions
• Request code review

Original prompt

In the test runner, at the moment, the bailout is not supported, I want you to propose me a minimal implementation that takes advantage of the abort controller of each single tests file in order to stop and propagate the failure once the first test of a test file fails
