Remove debugger id, use local frame id instead.

Why do we have 3 instrumentation callbacks in a row? What is
MainThreadDebugger's contract? I don't like the fact that it is visible in
core/.

         InspectorInstrumentation::didCreateScriptContext(frame, m_scriptState.get(), origin, m_world->worldId());
         frame->loader().client()->didCreateScriptContext(context, m_world->extensionGroup(), m_world->worldId());
     }
