Multiview transform feedback now passes if the transform feedback is
paused. Also updates the relevant validation. This aligns the
ANGLE_multiview validation with OVR_multivew and with the WebGL
extension spec.
This change allow us to combine multiple draw call validation updates
into one update function.
