In this change, an abstraction layer is added to the swapchain extensions. The extensions present_timing, present_id, image_compression_control, frame_boundary, and swapchain_maintenance1 are moved to the new extensions abstraction framework. Additionally, the compression control extension has been formalized in the layer as it is part of Vulkan spec so compression control guards have been removed.
