hwcontext_vulkan: use VkPhysicalDeviceTimelineSemaphoreFeatures

Browse Source 
VkPhysicalDeviceVulkan12Features isn't implemented on MoltenVK yet.
VkPhysicalDeviceTimelineSemaphoreFeatures is less versatile but
simple. None of device_features_1_1 nor device_features_1_2 has real
usage yet, keep the code for future.
