Vulkan: Allow pbuffer usage if no window support Vulkan allows rendering to non-swapchain images, so pbuffers can always be supported on every config. With this change, if the window system does not support a configuration, EGL_WINDOW_BIT is removed from the config instead of dropping the config entirely. Bug: chromium:1034840 Change-Id: Ib972ed8ddf7660c327123fa83ae0674456cf2a35 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2378921 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: back sept 10 - Jamie Madill <jmadill@chromium.org>
