Refactor Vulkan device and instance handling

Refactor Vulkan initialization to merge logical and physical device management into a unified `VkDevice` struct. Improved logging for Vulkan instance creation and surface management. Added methods to `VkPhysicalDevice` and `VkSurface` for more detailed querying of physical device capabilities.
