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.
Previously, the number of planes was incorrectly calculated.
The number of planes for non-linear images was the format
planes from wsialloc instead of the memory planes expected
by the implementation.
Additionally, the VK_IMAGE_CREATE_DISJOINT_BIT was based on
the format planes during image creation, instead of using the
allocation planes from wsialloc.
This commit corrects these issues by ensuring the plane count
and disjoint bit is set based on the appropriate memory planes.

Extends wsialloc_alloc to return whether or not the allocation will be
disjoint.
Groups wsialloc_alloc's return values to a struct.

A lot of the steps involved in creating a VkImage, allocating backing
memory, and binding the VkImage to the memory do not rely specifically
on Wayland features and could be common to other WSI backends.
This commit attempts to decouple the create_and_bind_swapchain_image()
function in the wsi/wayland/swapchain.cpp from Wayland and wsialloc
specific parts, and instead move the independent parts related to
external memory management to a new external_memory class. This will
allow the independent code to be re-used in future WSI backends.
