Switch to `Qt::PreciseTimer` for higher timer precision on Windows.
Using `Qt::PreciseTimer` for the Delayed Paint Helper improves the drawing framerate significantly, given that the system can handle it.
If the `stabilizerDelayedPaintInterval` config is set to below `20`, it actually already uses a high precision timer automatically, so this change only affects `stabilizerDelayedPaintInterval` of a value greater than or equal to `20` (which includes the default value).
Using `Qt::PreciseTimer` for the Stabilizer Sampler might subtly change the behaviour of the stabilizer due to a decrease in timer activation interval. (Before the change, on my system the timer would activate every 60-or-so ms when `stabilizerSampleSize` is set to `50`.)
I am not quite sure what would happen if the system is weak enough or is heavily loaded, and the performance cannot catch up with the timers.
