Matej Knopp 0d3941630d Revert "[macOS] Use CVDisplayLink to drive repaint (#49159)" (flutter/engine#51095)
The original PR assumed that `fml::TimePoint` has same base as
`CACurrentMediaTime()`. However due to recent change in Dart SDK that's
no longer true. Dart SDK
[replaced](https://dart-review.googlesource.com/c/sdk/+/348044?tab=comments)
call to `mach_absolute_time` with
`clock_gettime_nsec_np(CLOCK_MONOTONIC_RAW)`, while
`CACurrentMediaTime()` corresponds to `CLOCK_UPTIME_RAW`.

This needs to be fixed either in Dart SDK
https://github.com/dart-lang/sdk/issues/55071 or the original PR needs
to be relanded with appropriate conversions.

This reverts commit 8ff01af723be83ab019b0ddf7d64d8586d280186.
