Summary: In order to separate high-level properties of individual outputs from hardware-specific ones and access these, introduce a new generic class Output. Also make the DrmOutput class directly a child class of this generic class. The long-term goal is to get rid of the Screens global object on Wayland and instead directly work with Output objects on compositing level. This should enable us long-term to do direct scanout to hardware planes, what I predict needs this generic output representation at one point. Test Plan: Manually.
