Compose a layer with a picture profile passed in by an app
Forwards the picture profile to Composer HAL during composition. The
priority of a layer's profile, passed in by an app, plays a role in
deciding which requested profile actually get sent to Composer HAL
when limited picture processing hardware resources come into play.
