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.

If there exists two swapchains where one is a descendant of another, we
need to return VK_ERROR_OUT_OF_DATE_KHR error if the application tries
to present from the ancestor when the descendant has started presenting.
The has_descendant_started_presenting() function checks whether the
descendant has started presenting by looking for pending images in the
descendant's list of swapchain images. However, the descendant could
have already presented its pending image(s) before the ancestor arrives
at this check. In this scenario, the descendant will have marked the
swapchain image(s) as now free, and therefore when the ancestor looks
for pending images it will fail to find any. This causes the function to
incorrectly return false.
This bug can be resolved by creating a new boolean member variable to
track whether the swapchain has started presenting.

Fixes an issue, where acquire_next_image was always returning
VK_ERROR_OUT_OF_HOST_MEMORY when the swapchain had gone into a faulty

Adds an additional semaphore for every swapchain image to be waited for
before the present engine access an image. During a present request with
multiple swapchains, these semaphores are grouped together and are
signaled after the incoming pWaitSemaphores signal.

The swapchain teardown waits for pending images incorrectly. The
regression caused the wait to complete before pending images were
processed as well as a hang when all images are acquired by the
application or pending presentation. In this case the swapchain
teardown would hang waiting on the last image presented by a compositor
that would never be released.
Fixing this exposes additional hangs when swapchain images update the
free semaphore after being marked as free. There are also potential
hangs if multiple threads are waiting for all pending images or
acquiring an image at the same time. These issues are addressed by
serializing those actions with a mutex.

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.

Document instance_private_data and device_private_data.
Add additional utility containers (util::unordered_set,
util::unordered_map) that ensure that the storage containers
we use allow the use of the Vulkan allocation callbacks.
Additionally, ensure that these allocations don't throw in
case host runs out of memory but rather return the appropriate
Vulkan error code.
Also keep a copy the allocators so they can be used in other layer
functionality to facilitate following the Vulkan specification around
memory allocation.
Add additional utility util::optional that currently makes it easier
to handle errors in the containers described above.
Fix some small issues with the vkCreateInstance/vkCreateDevice
handling and ensure that vkDestroyDevice is called in the layer
handler.

Change util::allocator's create and destroy methods so that they can
allocate multiple objects, in line with the allocate and deallocate
methods of std::allocator.
Also add documentation for util::allocator and its methods.
Finally, use util::allocator in swapchain.cpp, rather than allocating
memory directly via VkAllocationCallbacks.

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.

The WSI layer may call pthread_cancel and kill the page flip
thread while it's still being used in Vulkan-API calls. This can cause the
layer to fail to clean up internal resources of the associated device,
leading to memory leaks. To resolve this, the layer now instead checks
if the page flip thread needs to end on every loop iteration. The
m_page_flip_semaphore has also been changed to a timed_semaphore to avoid
hanging indefinitely. In addition, m_page_flip_thread is now type
std::thread, which follows the gradual move towards C++ standard code
and moved to a private member function of the class.

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.
