📄 Description

Enable the build flag for llama.cpp to use CPU copy for multi-GPU scenarios.

~~Marking draft until I can validate this doesn't cause a significant performance hit for single GPU ROCm scenarios.~~

Update: perf results look good - no regressions detected in my testing.

Fixes #5087 #5450
