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.
