Vulkan: only request OPAQUE compositeAlpha on Android if no alpha Android used to only advertise INHERIT bit with the expectations that a Vulkan swapchain is only connected with SurfaceFlinger so that WM takes full control of the composition. That works fine till an encoder surface with EGL client (via ANGLE + KHR_swapchain) hits a suboptimal code path if the backing storage is RGBA but not RGBX. This change prepares for Android KHR_swapchain advertising OPAQUE bit for such surfaces as a hint to get RGBX backing. Bug: b/328125698, b/328122401 Test: encoder cts is passing, and no regression to ImageReader use cases Change-Id: Ia7f1c69935690f20efac6295eb824bee0d03eb07 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5378134 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org>
