vulkan: add initial Windows64 renderer backend and chunk texturing fixes

Browse Source 
Introduce a Windows64 Vulkan renderer implementation under C4JRender with the core runtime path for init, frame recording, and present.

Includes Vulkan swapchain/device setup, triangle pipeline state management, command-list draw replay, dynamic vertex streaming, texture object APIs, descriptor binding, alpha-test path, and UI overlay bridge integration.

Add Vulkan shader blobs for world geometry/UI and bridge header used by the Windows64 path.

Chunk rendering updates for Vulkan stability:

- keep compact/compressed chunk vertices disabled on Windows until the compact decode path is fully ported

- decode legacy no-mipmap U encoding (u + 1.0f flag) in the Vulkan vertex expansion path

- fix command-list replay so texture/alpha state is only restored when it was explicitly recorded, preserving runtime texture binds for chunk lists
