This is a rewrite of GHOST_ContextVK to align with Metal backend as described in #111389 - solution 3 with the adaptation that GHOST is still responsible for presenting the swap chain image and a post callback is still needed in case the swapchain is recreated. This PR also includes some smaller improvements in stability. Technical documentation: https://developer.blender.org/docs/eevee_and_viewport/gpu/vulkan/swap_chain/ * Renderpasses and framebuffers are not owned anymore by GHOST_ContextVK * VKFramebuffer doesn't contain a swap chain image. * Swapchain images can only be used as a blit destination or present source. Not as an attachment. * GHOST_ContextVK::swapBuffers would call a callback with the image the GPU module needs to blit the results to. * Clearing of depth/stencil attachments when no depth write state is set. * Enable VK_KHR_maintenance4 to relax the stage interface mapping. * Removes most vulkan validation warnings/errors. * Detection of frame buffer changes that needs to be applied before performing a command requiring render pass (draw/clear attachment) **Benefits** * Late retrieval of a swap chain image results in better overall performance as Blender doesn't need to wait until the image is presented on the screen. * Easier API and clearer state (transitions) * More control over Image layouts and command buffer states. (Better alignment with Vulkan API) Pull Request: https://projects.blender.org/blender/blender/pulls/111473
