#2590 Radeon mac optimization pass (#3277)

- Skip updating of reflection probes that are not the default probe when probe coverage is set to "None"
- enable RenderAppleUseMultGL and disable occlusion culling on Macs with AMD GPUs
- Reduce the number of texture decode threads on Macs with intel cpus.
- Move texture deletion to LLImageGL::updateClass and prevent textures from staying resident in vram longer than 3 frames
- Disable SSAO by default on Macs with intel CPUs
