[2D Renderer] Using more than one camera that renders out to a Render Texture creates GC Alloc every frame

Package: Scriptable Render Pipeline Universal

-

How to reproduce:
1. Open attached project "Universal Camera Garbage.zip" and scene "SampleScene"
2. Enter Play mode
3. Open Window -> Analysis -> Profiler
4. In Profiler search write "RenderPipelineManager"
5. Observe the GC Alloc for both processes

Expected result: no Garbage Collector allocations are made
Actual result: every frame 40B+ garbage allocations are made

Reproducible with: 2019.3.9f1 (7.1.8, 7.3.1), 2020.1.0b5, 2020.2.0a7 (8.0.1)
Could not test with: 2017.4, 2018.4 (2d renderer was not yet implemented)
