Instead of creating a single global fade surface across all outputs, create a separate surface for each output. This lets us individually fade each output (or block fading if the output has an inhibiting surface).
When there are client surfaces with valid idle inhibits present, fade out only the outputs those surfaces are not visible on. Then fade those out too, if the client terminates for some reason while the system is in sleep/idle/offscreen mode. This also fixes a potential issue if on multihead layout spanning a desktop wider than 8096 (or higher than 8096), the fade animation may not completely cover all surfaces. This assumes the output geometry doesn't change larger during the course of the fade animation.
