[vk] Implement Shader Read Barrier (#2671)

Adding the shader read barrier keeps every render/compute/transfer write visible before the image is sampled, so it prevents the “read-before-writes-finish” hazards. Without it you can get random stale frames, flickering post process passes, partially updated HUD textures, and corrupted depth-to-color conversions especially in scenes that render into an offscreen image and immediately feed that image to a shader (reflections, bloom, dynamic resolution, depth visualizers, etc.). This fix makes those R2T chains deterministic again across all Vulkan drivers.
