Merge branch 'rickard/timer-improvements'
OTP-14356
* rickard/timer-improvements:
Fix of later timer wheel
Minimum timeout position in each timer wheel
Manage timers to trigger at once in a slot similar to other timers
Introduce timer slot range counters
Timer wheel divided into a "soon wheel" and a "later wheel"
Remove unnecessary cancel callback from timer-wheel timers
Rearrange timer struct fields in order to simplify
Use timer wheel for short BIF timers
Use magic refs for BIF timers
Remove accessor BIF timer implementation
Fix aux-work timer implementation
