[DevTools] Migrate inspector-protocol/debugger tests to new harness

third_party/WebKit/LayoutTests/inspector-protocol/debugger/access-obsolete-frame.js

+(async function(testRunner) {
+  let {page, session, dp} = await testRunner.startBlank('');

dp stands for Debugger Protocol? Personally, I don't like abbreviations, but if
we want to be more succinct, might as well rename all testRunner -> t since it's
a convention with some JS testing libraries:

+
+  function logErrorResponse(response) {
+    if (response.error) {
+      if (response.error.message.indexOf('Can only perform operation while paused.') != -1) {
+        testRunner.log('PASS, error message as expected');
+        return;
+      }
+    }
+    testRunner.log('FAIL, unexpected error message');
+    testRunner.log(JSON.stringify(response));
+  }
+
+  dp.Debugger.enable();
+  dp.Runtime.evaluate({expression: 'setTimeout(() => { debugger; }, 0)' });
+
+  var messageObject = await dp.Debugger.oncePaused();
+  testRunner.log(`Paused on 'debugger;'`);
+  var topFrame = messageObject.params.callFrames[0];
+  var obsoleteTopFrameId = topFrame.callFrameId;
+
+  await dp.Debugger.resume();
+  testRunner.log('resume');
+  testRunner.log('restartFrame');
+
+  logErrorResponse(await dp.Debugger.restartFrame({callFrameId: obsoleteTopFrameId}));
+  testRunner.log('evaluateOnFrame');
+
+  logErrorResponse(await dp.Debugger.evaluateOnCallFrame({callFrameId: obsoleteTopFrameId, expression: '0'}));
+  testRunner.log('setVariableValue');
+
+  logErrorResponse(await dp.Debugger.setVariableValue({callFrameId: obsoleteTopFrameId, scopeNumber: 0, variableName: 'a', newValue: { value: 0 }}));
+  testRunner.completeTest();
+})
