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.

Implement support for VK_EXT_image_compression_control_swapchain
for both the Wayland and the headless windowing systems.
The extension can be conditionally enabled through the new build option
BUILD_WSI_IMAGE_COMPRESSION_CONTROL_SWAPCHAIN. Compiling with this
option enabled requires recent Vulkan headers (1.3.213)
Note also that support in the layer is enabled conditionally to
the ICD supporting VK_EXT_image_compression_control.
Update the WSIALLOC interface to version 2 and add support to
prefer selection of a format with the highest fixed rate compression
from the formats provided. This is used to pick a fixed rate
compression when VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT is
specified during swapchain creation.

Change the implementation to create wl_buffers immediately on client
side and defer the creation of wl_buffers on the server
when the first image is presented as that's when all buffered
requests will be flushed to the display
Additionally remove the swapchain event queue as we no longer need it to
dispatch any events

Fixes an issue where there was a chance that an exception would be
thrown when out of memory rather than returning an
appropriate VkResult code.
Additionally introduces a noncopyable utility class that can be used to
mark classes that should not have copy semantics

Moves the handling of frame done events from the swapchain object to the
surface object. This will prevent failures where a frame done event
arrives after the swapchain has been destructed but the surface hasn't.
Uses wayland_owners objects for managing the surface event queue and the
frame done event callback.

This change adds the use of zwp_linux_explicit_synchronization_v1 to
attach a Sync FD fence on presented image submitted to the compositor.
The change introduces the wsi/synchronization.hpp header and
implementation of the synchronization primitives used by WSI
implementations. Currently only Vulkan fences and fences exportable to
Sync FD are supported.

Replaces the default format used on swapchain image allocation. Instead
the format is negotiated between the supported formats by the Wayland
compositor the Vulkan ICD and any external system allocator.

Moves data and Wayland objects such as the registry to the
wsi::wayland::surface implementation. This also fixes a few issues
with queries where the Wayland display's default queue was wrongly
used and minimizes leaking of server memory from registry creation.
Moves the ownership of the zwp_linux_dmabuf_interface object to the
wsi::wayland::surface as it can be shared between swapchains.
Fixes issues with casting VkSurfaces in the Wayland backend that can
fail when using other layers that wrap the object.

A segfault can occur if wsialloc_delete is called but m_wsi_allocator's
ion field has not been allocated yet, as the function attempts to access
the ion properties.
This commit resolves the issue by changing m_wsi_allocator to an opaque
struct and removing the fd property, which was not being used.
wsialloc_new is then changed to return a pointer to the struct and
the swapchain then carries this pointer around, which will be
initialised to nullptr in the swapchain constructor.

Replace the implementation of how the roundtrips are done in
Wayland with one that is provided by the native Wayland client.
Additionally, fixes a small issue present in the Wayland swapchain
where WSI allocator would be freed by the destructor before
wsialloc_new was called resulting in an crash where WSI allocator
would be in an invalid state.

Very basic Wayland support is implemented by importing
memory with VK_EXT_image_drm_format_modifiers.
The current implementation requires an external system
memory allocator. An API for this allocator is defined
in util/wsialloc/wsialloc.h and an implementation using
the ION memory allocator is included.
Outstanding issues:
* This is an initial prototype for Wayland support and
has many outstanding TODOs which need addressing to
properly use the Wayland protocol.
* Using ICD Exported memory instead of a system allocator
is not implemented.
Wayland support is still experimental and outstanding issues
will be fixed in future commits.
