[Skills] Make Tracking Skill Configurable (#1784)

Added 1 rule per class that defines tracking distance multiplier for that class
Kept the defaults of 12 for ranger, 10 for druid, and 7 for bard

Created 1 method for determining class tracking distance multiplier
Created 1 method for determining if a class can track, based on multiplier

Updated tracking logic to use these methods to determine whether a tracking
packet should and can be sent or not.
