[vr] Register VR assets component from native

If running component updates in a background task we won't instantiate
an activity. As a consequence we won't register the VR assets component
and never get updates for it in the background. To solve this, register
the component in native.

The component gets only registered if the user has a Daydream headset
paired. Checking this is expensive. Thus, we save whether the component
should be registered in user preferences. At Chrome startup (which may
happen when running an update task in the background) read this flag
and conditionally register the component. Reading the flag took less
than 1 ms in my tests.
