SF: VsyncTimeline::isVSyncInPhase should use display rate

VsyncTimeline::isVSyncInPhase accidentally use the render rate
instead of the physical refresh rate to calculate the divisor.
This will break frame rate override when both the compositor
frame rate and an app frame rate are difrrent than the display refresh rate.
