Implement vkGetDeviceGroupSurfacePresentModesKHR,
vkGetDeviceGroupPresentCapabilitiesKHR, vkAcquireNextImage2KHR and
vkGetPhysicalDevicePresentRectanglesKHR function entrypoints in the
layer.
We assume that if the layer should not handle the surface the device or
instance should handle it as appropriate and fallback to this
implmentation.

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.

In vkCreateInstance:
- ppEnabledExtensionNames is checked to determine which window-system
platforms the layer should enable support for.
- support in the layer is always enabled if possible, even if this may
be provided by the ICDs. Platforms not supported by the layer should
still be correctly supported by the ICDs (untested.)
- pApplicationInfo is changed to bump the Vulkan API version
in order to enable instance extensions that are necessary for some
of the platforms implemented in the layer.
In vkCreateDevice:
- ppEnabledExtensionNames is extended with device extensions required
by the layer.
- if the extensions are not supported by the physical device, the
layer fails to initialize the device.

Move all WSI type specific calls to WSI factory methods. This
removes headless references in layer/ and allows for simpler
support of multiple windowing systems.

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.
