Migrates test/message/util_inspect_error and test/message/util-inspect-error-cause tests from the Python-based test runner to JavaScript, following the established pattern from #47498.

Changes:

• Moves test/message/util_inspect_error.js to test/fixtures/util/util_inspect_error.js (updates require path)
• Renames test/message/util_inspect_error.out to test/fixtures/util/util_inspect_error.snapshot
• Moves test/message/util-inspect-error-cause.js to test/fixtures/util/util-inspect-error-cause.js (updates require path)
• Renames test/message/util-inspect-error-cause.out to test/fixtures/util/util-inspect-error-cause.snapshot
• Adds test/parallel/test-node-output-util.mjs as the JS test runner using assertSnapshot.spawnAndAssert
• Removes the old .js and .out files from test/message/

Closes #47707 (partial - migrates util tests)
