Added new debug file with function that exposes the
DRM modifier of a swapchain image buffer.
Building the layer with DEBUG=1 flag will result
building this file and tests can now get the modifier
value for assertions.

- Add support for VK_KHR_swapchain_mutable_format extension to the Layer.
- Expose support for the VK_KHR_swapchain_mutable_format extension.
- Improve find_extension helper API to be spec-correct, const-correct,
and clearer by using the right base type (VkBaseInStructure for input,
VkBaseOutStructure for output),
and concise docs explaining it returns the first matching struct or nullptr.
- Correctly use image_create_info instead of m_image_create_info in
create_swapchain_image function for Wayland.

Fixes the following issues:
* For Wayland backend, populates the presentation feedback listener with all callbacks as it is considered a fault by the protocol to not implement those
* For Wayland backend presentation feedback listener, forwards the feedback_discarded event to present ID as there could be situations where previously submitted buffers are discarded, such as when swapchains are using the MAILBOX presentation mode.
* For all swapchains, communicate critical errors back to present wait extension as otherwise, all callers waiting that are waiting on present to be delivered in vkWaitForPresentKHR call will never exit.
* Expanded the implementation in vkWaitForPresentKHR to be able to return critical swapchain errors if they have occured during the wait time.
* Fix issues in present ID where infinite waits could result in the vkWaitForPresentKHR call returning immediately due to UINT64_MAX timeout resulting in overflowing the system clock used in std::condition_variable

The FIFO implementation in the Wayland backend that uses the
presentation thread is not technically Vulkan conformant. This commit
enables a true FIFO implementation that is conformant to the Vulkan
spec by blocking in the vkQueuePresent path. On Wayland this is
achieved by having the main thread wait for the frame_done event to be
sent by the compositor. This was already used in FIFO before but
previously it would be the presentation thread that would block.
This implementation is now used by default.
The downside of this approach is that it has a significant performance
impact due to blocking the main thread.
Users wishing to continue using the presentation thread
implementation to achieve better performance can still do so through
a new build option `ENABLE_WAYLAND_FIFO_PRESENTATION_THREAD`.
The README has also been updated to document the FIFO shortcomings.

The layer needs functionality that is not part of Vulkan 1.0 and is
provided by either Vulkan 1.1 or separate Vulkan extensions.
The layer used to solve this issue by bumping the API version passed
by the application in VkCreateInfo to 1.1 if this was set to 1.0.
This workaround does not seem to be working anymore with recent
versions of the loader. Fortunately, the loader now allows layers
to change the extension lists passed by the application.
This patch changes the layer to use this approach and removes the
API bump logic.
Documentation is updated accordingly.

- Document option to provide a custom implementation of the wsialloc.h
interface and to disable support for VK_EXT_headless_surface
- Fix link to Vulkan Loader documentation

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.

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.
