llama.cpp b10938 adds Vulkan queuesubmit mutex to fix NV driver bug

from English

The llama.cpp project released version b10938, which includes a workaround for a NVIDIA driver bug affecting Vulkan execution. The update introduces a mutex around the queuesubmit operation to prevent synchronization issues when two queues on the same VkDevice submit simultaneously.

Adds a mutex around Vulkan queuesubmit to resolve internal synchronization breaks caused by concurrent queue submissions on NVIDIA hardware.
Provides binaries for macOS (Apple Silicon and Intel), Linux (CPU, Vulkan, ROCm, OpenVINO, SYCL), Android, Windows (CPU, CUDA 12/13, Vulkan, OpenCL, OpenVINO, SYCL, ROCm), and openEuler platforms.

This release ensures stable Vulkan performance on affected NVIDIA drivers by mitigating the identified synchronization defect.
