kernel: Fix sleep timing accuracy (#2828)

Browse source 
* kernel: Fix sleep timing accuracy

This commit corrects some mistake while comparing reversing of kernel
13.x with our own.

WaitAndCheckScheduledObjects timing accuracy was also improved.

* Make KTimeManager.WaitAndCheckScheduledObjects spin wait for sub milliseconds

Fix performance regression on Pokemon Let's Go games and possibly
others.

* Address rip's comment

* kernel: Fix issues with timeout of -1 (0xFFFFFFFF)

Fixes possible hang on Pokemon DP and possibly others
