To validate Adaptive-Sync's Flipline mode, make sure that flips happen at
flipline decision boundary.

Example: if monitor vrr range is 40 - 60Hz and

* flip at refresh_rate > 60Hz:
        Flip should happen at the flipline boundary & returned refresh rate
        would be 60Hz.
* flip at refresh_rate == 50Hz:
        Flip should happen right away so returned refresh rate is 50Hz.
* flip at refresh_rate < 40Hz:
        Flip should happen at the vmax so the returned refresh rate
        would be 40Hz.

  tests/kms_vrr: Add new subtest to validate Flipline mode
