This PR implements CreatureStaticFlags4::NO_MELEE_APPROACH

This could also mean the exact opposite: Melee combat is disabled, but the Creature tries to run into melee range, similar to NO_MELEE_FLEE except it approaches instead of flees. I'm not sure

The proper name of this flag is No Melee (Approach) - autoattacks are disabled but creatures chase as-if it wasnt

No Melee (Flee) - autoattacks are disabled and creature runs away (the critter behavior) there are no non-critter and non-pet creatures before cataclysm that use this flag (fleeing part of this flag is disabled/overriden if the creature is a pet (including pet of another creature, not just player)

Cataclysm has one https://www.wowhead.com/npc=40168/corrupted-dryad

Thanks a lot, I'll update the code!
