llama.cpp update optimizes tensor operations with reduced synchronization

A recent update to the llama.cpp project, specifically pull request #20793, introduces significant optimizations for tensor operations. These changes aim to reduce synchronization overhead during split computations, particularly benefiting CUDA backends by replacing synchronous copies with asynchronous ones. The modifications also enhance backend detection to prevent linking conflicts and allow for more general opt-in relaxation of explicit synchronization requirements, potentially benefiting other backends like Vulkan.
