  Make MockGamepadProvider robust so that it doesn't end up crashing the test runner

Reviewed by David Kilzer.

This change adds more state to MockGamepadProvider so that it can track the gamepads
that were connected before the GamepadProviderClient starts monitoring. Before this change,
a simple snippet like:
<script>
  testRunner.setMockGamepadDetails(0);
  testRunner.connectMockGamepad(0);
  addEventListener('gamepadconnected', () => {});
</script>

would crash the test runner.
