backend/native: Set CRTC gamma once per frame

Browse Source 
Before we received new gamma updates via D-Bus and posted the update to
KMS directly. This won't be possible with atomic KMS, since one can only
update the state of a CRTC once per cycle.

Thus, to handle this, when configured by D-Bus, only cache the value,
and mark it as invalid. The next frame, the native renderer will pick
up the newly cached gamma value and configure the CRTCs accordingly.
