Implement Gruul's Lair strategy (#1647)

* Implement Gruul's Lair strategy

* minor non-gameplay tweaks to code

* Use multiplier for tank assist

* HKM warlock & Gruul tank tweaks

* Fixed declarations

* rewrote HKM + minor Gruul tweaks

* Update PlayerbotAI.cpp

* modernize code and address comments

* clean ups to tank logic

* Oops.

* Remove post-move delay

For actions like positioning bosses, the standard post-movement delay should be overridden IMO since a player would be sequencing their actions in this type of situation

* Update RaidGruulsLairActions.cpp

* Replace break statements with return true

* enum class to enum

* moved all isuseful checks to triggers

* Split multipliers and improved banish logic

* Update for comments

* changes to int

* use helpers for marking icons

* address compile errors

* correct MoveTo and use RTI helper

* address comments and rename actions/triggers

* adjust alignment of location constants

* fix some crappy returns

* allow return true when changing targets

* change indents and move enums inside namespace

* style changes, trim trailing whitespaces, address comments
