[WebGL] [URP] Large memory allocations on builds when many objects are visible in the viewport while using integrated GPU



Reproduction steps:
1. Open the attached project ("")
2. Change the build target to WebGL
3. Make a WebGL build and run it
4. Move around the game by dragging the right-mouse button

Expected result: Memory allocation remains more or less constant
Actual result: Additional 1-2GB of memory is allocated when many objects enter the viewport

Reproducible with: 2019.3.7f1, 2020.1.0b3, 2020.2.0a4
Not reproducible with 2018.4.19f1
Couldn't test with 2017.4 (URP package is not supported)

Reproducible with package versions: 5.13.0 (LWRP), 8.0.1 (URP)
Not reproducible with package versions 4.10.0, 5.10.0 (LWRP)

Tested on: Chrome (80.0.3987.149), Firefox (74.0)

1. The issue only reproduces on integrated GPUs (tested with Intel UHD Graphics 630)
2. The issue does not reproduce in Editor and Standalone (Windows) builds (tested both Mono and IL2CPP backends)
