[SRP] unity_LightIndices[1] are identical to every object and are set per frame



How to reproduce:
1. Open the attached "case_1155879-LightIndices" project
2. Move around the Scene and inspect how the spheres are lit

Expected results: The lighting should not change
Actual results: The lighting changes and flickers

Reproducible with:
2019.1.6f1 (with SRP 5.16.1)
2019.2.0b6, 2019.3.0a6 (with SRP 6.7.1)

Note: By using the Frame Debugger you can notice that every rendered object has identical unity_LightIndices[1]. This data is set every frame instead of every draw and can change based on the Camera's position.

    The indices still fail when the SRP Batcher isn't active, when more than one material is used. It fails in so many ways that I don't know where to begin. Do some tests!

    Although this issue is listed under Scriptable Render Pipeline Lightweight, it affects all SRPs. It's not a bug in the LWRP package, but in Unity 2019.
