intel-virtual-overlay: Reset damage across modesets 

Some versions of the Xserver lose Damage tracking across the modeset,
causing a loss of damage notifications and repainting to cease on the
virtual outputs. We can workaround this by reattaching the damage every
time we receive notification that the local Screen configuration
changes.
