compositor-drm: Move KMS API use to separate file

Browse Source 
Create a new file which handles most of the actual KMS API use. This
covers the property handling (in which we map between KMS properties and
our internal representations), as well as actually applying state
through atomic modesetting or the legacy SetCrtc/PageFlip/DPMS APIs.
