vulkan: Separate debug utils logic from VulkanInitialization (#4609)

* vulkan: Separate debug utils logic from VulkanInitialization

Also checks for VK_EXT_debug_utils existence instead of force enabling it and allow possible error during messenger init

* Address gdkchan's comment

* Use CreateDebugUtilsMessenger Span variant
