Dynamic Creature/Go spawning:

 - True blizzlike creature spawn/respawn behavior - new creature = new object
 - Toggleable spawn groups (with C++/SAI/command options to use them)
 - Custom feature: dynamic spawn rate scaling. Accelerates respawn rate based on players in the zone.
 - Backward compatibility mode (set via group and for summons)
   to support creatures/gos that currently don't work well with this
   (this should be removed once the exceptions are fixed)

Fixes and closes #2858
Tags #8661 as fixable.
Fixes and closes #13787
Fixes #15222.

(cherry picked from commit 59db2eeea0a35028779fd76372ae06cc98c8086f)
