Do not defer clear if FBO attachment is AHB image When application uses Android Hardware Buffer (AHB) image as the Framebuffer Object (FBO) attachment, it is possible the app doesn't call glReadPixels to fetch the FBO color. In this case deferred clears will not be flushed when the app reads the FBO pixel color, and the app will read the old FBO color. This CL fixes the issue by flushing the glClear calls immediately when any of the FBO color attachments is AHB image.
