Realtime Reflection Probe causes a big slowdown on Mali devices with OpenGLES3
To reproduce:
1. Open the attached project;
2. Open Quality Settings > Check if "Realtime Reflection Probes" is enabled in Android's quality level;
3. Switch Graphics API to OpenGLES3
4. Build and run "Farm_Universal_Setup_Demo" scene on Mali devices
Expected result: no performance spikes on Mali devices
Actual result: huge performance spikes every frame, FPS drops from 60fps to ~7fps in 2-3seconds
Reproduced with: 2019.3.5f1, 2019.3.9f1, 2020.2.0a5, 2020.2.0a6
Reproduced with URP: 7.3.1, 7.x.x/release branch (7.4.0), SRP Master (9.0.0-preview13)
Devices under testing:
Reproduced with:
Samsung Galaxy Note 9, Mali-G72, Android 10

Not reproduced with:
Samsung Galaxy S9, Adreno 630, Android 9.0.0

Resolution Note:
By design: reflection probe has clipping far plane set to 1000, so it essentially renders the entire world scene 6 times, that's 11 million triangles.
