Unity default "Particles/Standard Surface" Shader allocates too much memory compared to other Shaders
How to reproduce:
1. Open the attached "case_1411407" project
2. Open the "Window -> Analysis -> Memory Profiler" window from the menu
3. Capture a new Snapshot and select it
4. Select the "Shader" object category in the Tree Map
5. Observe the displayed object sub-categories of the "Shader" category
Expected result: Maximum size of the "Particles/Standard Surface" Shader is ~2 MB
Actual result: "Particles/Standard Surface" Shader takes 30-72 MB (depends on Unity version) compared to other Shaders, which maximum size is ~2 MB
Reproducible with: 2019.4.39f1, 2020.3.34f1, 2021.3.3f1, 2022.1.1f1, 2022.2.0a13
Note: Shader size trend:
2019.4.0f1 - 35.2 MB, 2019.4.39f1 - 71.2 MB
2020.3.34f1 - 71.8 MB
2021.3.3f1 - 72.5 MB
2022.1.1f1 - 72.2 MB

Resolution Note:
Hi,
This shader has a lot of variants therefore takes up a lot of memory in the Editor.
However, only used variants should take up space in player data. So memory usage should be much lower there unless lots of particle variants are being used.
