How to reproduce:
1. Open attached project
2. Open XR settings and notice that Multi Pass is not greyed out
3. Build to Android/iOS device with VR Support enabled and notice that one eye is rendered only

Expected result - Either Unity should not let build with multi-pass (as it did prior to 2019.2.0a6) or should work without issues while using LWRP+Multi-Pass
Actual result - Unity allows to build VR app with LWRP+Multi-Pass and this result into one eye rendered only on Mobile VR applications

Regression introduced in - 2019.2.0a6
Reproducible with - 2019.2.0a13, 2019.2.0a6
Not reproducible with - 2019.2.0a5

Reproduced with LWRP 5.2.3 and 6.5.3
