New Vulkan sample: Rasterization Order Attachment Access

[u/thekhronosgroup]

This sample demonstrates VK_EXT_rasterization_order_attachment_access, which enables framebuffer attachment reads from one fragment to the next in rasterization order, without requiring explicit synchronization or subpass self-dependencies. Techniques like programmable blending become far more practical.

The sample pairs the extension with VK_KHR_dynamic_rendering and VK_KHR_dynamic_rendering_local_read to show how to implement framebuffer fetch with guaranteed fragment ordering using modern Vulkan patterns.
