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.

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.
