HLE: Add OS-specific precise sleep methods to reduce spinwaiting (#5948)1.1.1094
* feat: add nanosleep for linux and macos
* Add Windows 0.5ms sleep
- Imprecise waits for longer waits with clock alignment
- 1/4 the spin time on vsync timer
* Remove old experiment
* Fix event leak
* Tweaking for MacOS
* Linux tweaks, nanosleep vsync improvement
* Fix overbias
* Cleanup
* Fix realignment
* Add some docs and some cleanup
NanosleepPool needs more, Nanosleep has some benchmark code that needs removed.
* Rename "Microsleep" to "PreciseSleep"
Might have been confused with "microseconds", which no measurement is performed in.
* Remove nanosleep measurement
* Remove unused debug logging
* Nanosleep Pool Documentation
* More cleanup
* Whitespace
* Formatting
* Address Feedback
* Allow SleepUntilTimePoint to take EventWaitHandle
* Remove `_chrono` stopwatch in SurfaceFlinger
* Move spinwaiting logic to PreciseSleepHelper
Technically, these achieve different things, but having them here makes them easier to reuse or tune.
