Debug build is crashing. I'm going to revert. PTAL.

Thank you for the information. I will confirm today.

The socket port implementation can only hold one JSC::RemoteInspector::Client.
However, when two or more WebContext(WebProcessPool) were created, each would attempt to set the JSC::RemoteInspector::Client, resulting in the above assertion.

One test before "animation/cross-fade-background-image.html" is "animation/crash-on-removing-animation.html".
This test caused WTR to restart, which generated a second WebContext, thus causing the above assertion.
Also, when "New Window" was executed in MiniBrowser, multiple WebContxts were created and the same assertion occurred.

To fix this problem, in the WebProessPool::platformInitialize(), do not create a new AutomationClient if JSC::RemoteInspector::Client is already set.
This means that only the first generated WebContext can be manipulated by WebDriver.
