Add screen tap WebVR tests

Add screen tap WebVR tests

Adds two new WebVR e2e tests verifying that screen taps are registered in VR
when using Cardboard but not Daydream View.

Also increases the timeout of certain Javascript executions since 50 ms was
sometimes (although rarely) causing flakiness.

Re-names the VR restrictions to more clearly differentiate between restrictions
on Daydream-readiness and restrictions on the currently paired viewer.
