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

third_party/WebKit/LayoutTests/inspector-protocol/runtime/runtime-console-memory.js

+(async function(testRunner) {
+  let {page, session, dp} = await testRunner.startHTML(`
+    <div id='mydiv'>div from page</div>
+  `, `Tests that console.memory works correct.`);

+  dp.Runtime.enable();

+      memory = console.__lookupGetter__('memory').call(location);
+      console.log(memory.constructor.constructor('return document.querySelector("#mydiv").textContent')());

The constructor is a function, so constructor.constructor is Function? What is
this testing?

I have no idea, but I preserved the original code.

+    }
+  `);
+  var result = await dp.Runtime.onceConsoleAPICalled();
+  testRunner.log('=== Dump console message ===');
+  testRunner.log(result.params.args[0].value);
+  testRunner.completeTest();
+})
