How to reproduce:
1. Open the attached "IndirectDrawTest" project and "Test" scene
2. Open Game view window and notice that there are four Spheres. Leftmost one is drawn using a mesh renderer component and other three are drawn with DrawMeshInstancedIndirect

Expected result - All the Spheres reflect to Light Probes and Reflection Probes
Actual result - The instanced Spheres do not react to Light Probes and Reflection Probes when in a Forward Rendering mode

Reproducible with - 2017.3.0a7, 2017.2.0b11, 2017.1.1p1, 5.6.3p3

Notes:
1. In a Deffered Rendering, Instanced objects do not ignore Reflection Probes, but do ignore Light Probes
2. Issue is reproducible when using both Graphics.DrawMeshInstanced and Graphics.DrawMeshInstanceIndirect
