[vk] Unify RAII in Vulkan (#2679)

This PR consolidates Vulkan RAII on video_core/vulkan_common/vulkan_wrapper.h’s vk::Handle and remove the unused duplicate src/video_core/vulkan_common/vulkan_raii.h, reducing confusion and maintenance. Swapchain now uses RAII‑managed per‑image semaphores and clears them in Destroy(), providing correct present synchronization and automatic cleanup. Expected result: simpler lifetimes, fewer leak risks, and more stable presentation with negligible overhead.
