Christian Hergert dac0b7d609 macos: use video mode for refresh rate and interval
Using the mode allows better detection of refresh rate and refresh
interval for the CVDisplayLink bridge to GdkFrameClock. Using it can help
ensure that our 144hz displays can actually reach that rather than falling
back to just 60hz.

This will also need future commits to rework the displaylink source to be
per-monitor.
