[Android]Compute Shader fails to compile when using it on Android with Mali GPU
Steps to reproduce:
1. Open user's attached project
2. Build it to Android
3. Run the app with the LogCat turned on
4. Notice the Compute Shader fails to compile due to "'local_size_x' qualifier value (1024) exceeds the maximum supported size (128)."
Expected results: Compute Shader is compiled
Actual results: Computed shader fails to compiled die to qualifier support size being only 128
Reproducible with: 2019.3.0f6,
LogCat doesn't show info in 2020.1.0a21
VLNQA00231, Huawei HUAWEI Mate 20 Pro (LYA-L29), Android 9, CPU: HiSilicon Kirin 980, GPU: Mali-G76
VLNQA00175, Samsung Galaxy Note9 (SM-N960F), Android 9, CPU: Exynos 9 Series 9810, GPU: Mali-G72
Note: This issue only reproduces with Mali devices since Adreno limits to 1024x1024x64, Mali to 128x128x128. I couldn't test with 2018.4 and due to errors. Sometimes LogCat will not show the "'local_size_x' qualifier value (1024) exceeds the maximum supported size (128)." line, however, the Shader still doesn't compile. Logcat information is attached below

Resolution Note:
Mali GPUs are not supported and might not be supported in the future as they don't support Shader Storage Buffer Object (SSBO). The addition of CPU particles might change this in the future, but that's not guaranteed.
