Message : Reland: [Vulkan] Add DisplayVkNull Currently all DisplayVk implementations depend on VK_KHR_swapchain and VK_KHR_surface extensions. When running Chromium on Fuchsia these extensions are never used (content is shown on the screen using ImagePipe API without dependency on swapchain). ANGLE still depended on these extensions for DisplayVkFuchsia. This CL adds DisplayVkNull, which allows to run ANGLE without dependency on swapchain. It's usable only offscreen and cannot present content on a surface. Bug: chromium:1203879 Change-Id: I5cadcdf46ed1cfb5ebb3cb69dbfef063e9e2b826 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3012368 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
