[Backport] Instanced URP Shaders using Spherical harmonics variables causes long initial mesh render time when used in WebGL

--

-

How to reproduce:
1. Open the attached project "DrawMeshLongFirstCallURP.zip"
2. Open the "BrokenShaderScene" Scene
3. Open the Build Settings (File > Build Settings...)
4. Make sure the WebGL platform is selected
5. Build And Run

Expected result: Both Shader's load time is close to each other
Actual result: The Shader that uses the Spherical harmonics variables loads 19 seconds later

Tested on: Google Chrome version 99.0.4844.83 (Official Build) (x86_64), Safari version 15.3 (17612.4.9.1.8)

Reproducible with: 2019.4.37f1, 2020.3.33f1, 2021.2.15f1, 2021.2.19f1, 2021.3.0f1, 2022.1.0b15, 2022.2.0a10

Notes:
- Not reproducible on Safari
- Reproducible on Google Chrome
- Only reproducible on MacOS

  1. Resolution Note (2022.1.X):

    2022.1 is no longer accepting changes, so this port is not able to be executed for that branch. Cancelling port.
