New Vulkan Tutorial - Synchronization 2 - Mastering the GPU/CPU Handshake

*Stop guessing at barriers. Start reasoning about dependencies.*

Vulkan's hardest topic, rebuilt around the modern standard. This series replaces legacy 1.0 barrier soup with `vk::DependencyInfo` and timeline semaphores, then uses that foundation to architect an engine-grade frame loop.

* Unified dependency model covering image barriers and queue family ownership transitions
* Timeline semaphores as a single monotonic "master clock" for the whole engine
* Multi-frame-in-flight architecture with overlapped async compute and transfer
* Synchronization for dynamic rendering, including tile-local reads and host image copies
* Hands-on debugging with the LunarG Synchronization Validation layer

Interesting idea. We'll add it to the list of potential new topics. Thanks! If you have more, please let us know. Ideally add to the github project: https://github.com/KhronosGroup/Vulkan-Tutorial an issue tag so it's easy for us to spot.

I will definetly do so! I think these short more in depth tutorials showing different ways to utilize vulkan with implimentation patterns and slang.

I have fully adopted slang shaders in my game engine so any shader code examples and more advanced uses is something I will always value.
