kms: Allow setting the "VRR_ENABLED" property on a CRTC

Browse Source 
Add functions to update and monitor the value of the "VRR_ENABLED"
KMS property.

This requires the addition of functions to process CRTC property
updates in both the atomic and the simple KMS backends. The
implementation is similar to the implemention of processing
connector updates.
