Decouples the swapchain images and their memory binder/allocator logic into separate classes. This allows us to reduce code duplication across different backends that use the same type of allocation logic and also allows us to make use of RAII to release the resources for swapchain images. The swapchain_base and other swapchain classes have been refactored to handle the new swapchain images. The patch makes the following adjustments: * Introduces a new swapchain_image class that holds all swapchain image resources * Introduces a swapchain image factory class that constructs swapchain images * Introduces a Vulkan image handle class that is responsible for constructing VkImage handles * Introduces a new interface that describes how swapchain backing memory is being allocated * As part of this backing memory interface, introduces device and external (wsialloc) backing memory classes * Introduces a new interface that holds swapchain image data like wl_buffers * Refactors lots of swapchain image parts out of the base swapchain class and moves it into the respective backends to simplify the swapchain classes.
