feat: replace deletion_queue with smart pointers

[Gr-i-niy]

Replace raw Vulkan handles with smart wrapper classes for automatic resource management. Updates command pools, images, and fences to use RAII pattern, eliminating manual cleanup code and reducing memory leaks.

Pull Request Overview

This PR replaces manual deletion queues with RAII smart pointer wrappers for Vulkan resources to simplify cleanup and reduce memory leaks. Key changes include the introduction of Vulkan smart wrapper classes for fences, semaphores, command pools, images, and buffers, as well as updates throughout the engine to use these wrappers in place of raw Vulkan handles.

• Introduced RAII wrapper classes in vk_smart_wrappers.h
• Updated vk_engine.h and vk_engine.cpp to use smart pointers for resource management
• Modified command buffer and pipeline initialization to work with the new smart wrappers

• Manual destruction of command pools in the cleanup routine is redundant since the VulkanCommandPool destructor already handles resource deletion. Removing this manual call will help prevent potential double free errors.

if (_frame._commandPool) { vkDestroyCommandPool(_device, _frame._commandPool->get(), nullptr); }
