Move ui_test_utils::RunMessageLoop to test_utils so that it can be reused by content_browsertests.

 // Base class for tests wanting to bring up a browser in the unit test process.
 // Writing tests with InProcessBrowserTest is slightly different than that of
 // other tests. This is necessitated by InProcessBrowserTest running a message
 // loop. To use InProcessBrowserTest do the following:
 // . Use the macro IN_PROC_BROWSER_TEST_F to define your test.
 // . Your test method is invoked on the ui thread. If you need to block until
 //   state changes you'll need to run the message loop from your test method.
 //   For example, if you need to wait till a find bar has completely been shown
-//   you'll need to invoke ui_test_utils::RunMessageLoop. When the message bar
-//   is shown, invoke MessageLoop::current()->Quit() to return control back to
-//   your test method.
+//   you'll need to invoke content::RunMessageLoop. When the message bar is
+//   shown, invoke MessageLoop::current()->Quit() to return control back to your
+//   test method.
 // . If you subclass and override SetUp, be sure and invoke
 //   InProcessBrowserTest::SetUp. (But see also SetUpOnMainThread,
 //   SetUpInProcessBrowserTestFixture and other related hook methods for a
 //   cleaner alternative).
 //
 // Following three hook methods are called in sequence before calling
 // BrowserMain(), thus no browser has been created yet. They are mainly for
 // setting up the environment for running the browser.
 // . SetUpUserDataDirectory()
 // . SetUpCommandLine()
