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.

The wsialloc interface now has explicit versioning which is used to
ensure that wsialloc implementations are compatible with the interface.
wsialloc implementations should define which version they are using and
upon version mismatch compilation will fail.
Also:
- add new WSIALLOC_MAX_PLANE macro to define the maximum number of
planes that the wsialloc should support.

Reduce the number of functions that are exported by the layer. This
helps resolve dynamic linking issues where multiple functions are named
the same in different shared libraries. Also add function specifiers and
calling conventions to all extern "C" functions.

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.

Defines an abstract wsi::surface object to be implemented by each WSI
backend. This object is then associated with the corresponding VkSurface
object in the instance specific data.
To keep track of these objects the layer now intercepts
vkDestroySurfaceKHR, while specific surface creation entrypoints are
intercepted by individual WSI backends.
In addition this change should allow for fixing incompatibility issues
with layers that wrap VkSurface which breaks casting to the Loader's ICD
VkSurface type.
Make greater use of util::unique_ptr and allow for such pointers to be
constructable when casting derived types.

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.

Add util::vector to provide functionality similar to std::vector,
i.e. growable arrays. util::vector does its allocations via a custom
allocator provided via VkAllocationCallbacks and provides methods to
check whether the allocation fails, e.g. try_push_back() returns false
when the allocation fails and replaces std::vector's push_back() method
that would rather raise an exception to report an allocation failure.
Note that this commit switches on exceptions in the layer by removing
the flag -fno-exceptions.
util::vector is also used to store swapchain images.

This commit adds the initial sources for the vulkan-wsi-layer project:
a Vulkan layer which implements some of the Vulkan window system
integration extensions such as VK_KHR_swapchain.
The layer is designed to be GPU vendor agnostic when used as part of the
Vulkan ICD/loader architecture.
The project currently implements support for VK_EXT_headless_surface and
its dependencies. We hope to extend support for further platforms such
as Wayland and direct-to-display rendering in the future.
This initial commit collects contributions from different individuals
employed by Arm.
More information on the project (building instructions, how to
contribute, etc.) can be found on the README.md file at the top of the
project tree.
