Right now there is actually an infinite loop.
   -MashBrowserTestsMain::CreateServiceManagerConnection is registered as the content::ServiceManagerConnection factory.
   -BrowserMainLoop goes to init a ServiceManagerContext triggering the factory.
   -But the factory we registered ends up calling ServiceManagerConnection::Create. Which calls the factory.... thereby infinitely looping.

When this isn't occurring there is a crash in the GpuService as we are attempting to start all services in the same process.

We only want to start the test case, normally a child process, in the same process as the host.

All services should still be spun up in their own processes
