Vulkan: Submit semaphores from glWaitSemaphoreEXT & glSignalSemaphoreEXT Implement submission of client semaphores passed to glWaitSemaphoreEXT & glSignalSemaphoreEXT. This also relaxes the expectation that we will not flush() if there are no commands. Signaling semaphores in particular requires queue submission irrespective of whether there are any command buffers to submit. If there are neither commands nor semaphores, we can still skip queue submission. WebGL runs in Chrome with ANGLE & Vulkan interop as of this patch, albeit with incorrect synchronization due to texture barriers not being implemented yet. Quite a few flags are needed to try this: GN args: angle_vulkan_conformant_configs_only=true chrome \ --enable-features=UseSkiaRenderer,UiGpuRasterization \ --enable-gpu-rasterization \ --enable-oop-rasterization \ --enable-vulkan \ --use-gl=angle \ --use-angle=vulkan Bug: angleproject:3289 Change-Id: I3d49c230a2fbf0cd2a2b943b05ded0e4604cc313 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1623815 Commit-Queue: Michael Spang <spang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
