feat: Implement core Vulkan initialization and rendering loop
This commit lays the foundational groundwork for the Vulkan rendering backend.
Key changes include:
1. **Platform Layer (`rcore_desktop_glfw.c`):**
* `InitPlatformVulkan`: Implemented to correctly create a `VkInstance` with necessary GLFW extensions and validation layers (if `RLGL_ENABLE_VULKAN_DEBUG` is defined). It also creates a `VkSurfaceKHR` using GLFW. These handles are passed to the core Vulkan layer.
* `ClosePlatformVulkan`: Updated to properly destroy the `VkInstance` and `VkSurfaceKHR`.
2. **Vulkan Abstraction Layer (`rlvk.c`, `rlvk.h`):**
* `rlvkInit`: Implemented the core Vulkan setup:
* Physical device selection (preferring discrete GPUs).
* Logical device creation with graphics and present queues, and swapchain extension.
* Swapchain creation (images, image views).
* Render pass creation (with color and depth attachments).
* Depth buffer resource creation (image, memory, image view).
* Framebuffer creation for each swapchain image.
* Command pool and command buffer allocation (one per swapchain image).
* Synchronization primitives (semaphores for image acquisition/render completion, fences for command buffer completion).
* `rlvkClose`: Updated to destroy all Vulkan resources created in `rlvkInit` in the correct order.
* `rlvkBeginDrawing`: Implemented to handle frame synchronization (wait for fence, acquire next swapchain image), begin the command buffer, and begin the render pass (using the clear color set by `rlvkClearBackground`). Viewport and scissor are set.
* `rlvkEndDrawing`: Implemented to end the render pass, end and submit the command buffer (signaling appropriate semaphores and fence), and present the image. Handles frame advancement.
* `rlvkClearBackground`: Implemented to store the clear color you provide, which is then used by `rlvkBeginDrawing`.
With these changes, a raylib application compiled with `GRAPHICS_API_VULKAN` can initialize a Vulkan context, open a window, clear the background to a specified color, and shut down cleanly. Actual object rendering (shapes, textures, models) is not yet implemented in Vulkan and will be part of subsequent work.
