[Android][OpenGL] Crash when reading and writing the same RWTexture in a Compute Shader
How to reproduce:
1. Open the user's attached "sspr.zip" project
2. Open the Build Settings (File->Build Settings...)
3. Switch Platform to "Android"
4. Open the Player Settings (Edit->Project Settings...->Player)
5. In the Android tab, "Other Settings" section change active Graphics API to "OpenGLES3"
6. Build and Run the "SampleScene" on an Android device
Expected results: Crash
Actual results: No crash
Reproducible with: 2020.3.34f1
Not reproducible with: 2021.3.2f1
Unable to test with: 2019.4.38f1 because of error CS0234, 2022.1.0f1, 2022.2.0a12 because of the error CS0122: x is inaccessible due to its protection level
Reproducible with:

- Thresholds are no longer automatically calculated after deleting Motion fields in Blendtrees
Resolution Note (2022.2.X):
The shader is using a format that OpenGL ES 3.1 does not support for read and write access in the same shader.
Only R32 formats can be used that way. (GLSL ES 3.1 spec chapter 4.9 "Except for image variables qualified with the format qualifiers r32f, r32i, and r32ui, image variables must specify either memory qualifier readonly or the memory qualifier writeonly")
You should get the following warning in the Unity Editor's shader inspector: "Shader warning in 'SSPRReflectionColor': HLSLcc: The resource 'Result' uses an unsupported type/format for read/write access at kernel CSBlur (on gles3)"
