There were several issues with KV defragmentation with quantized KV:
ggml_cpyfrom quant to quant, which was not supported in the CUDA backendggml_backend_schedcannot fallback to the CPU backend either when the destination is pre-allocated, which was not correctly detectedThis fixes the issues in
ggml_backend_schedand adds support to the CUDA backend forggml_cpywhen the types are the same and the tensors are contiguous (usingcudaMemcpyAsync).Other backends may also be affected.
Fixes #9314
