fix(Scripts/Naxxramas): Razuvious' Death Knight Understudy RP

[sogladev]

Changes Proposed:

This PR proposes changes to:

• Core (units, players, creatures, game systems).
• Scripts (bosses, spell scripts, creature scripts).
• Database (SAI, creatures, etc).

Adds Out of Combat RP to Razuvious and his Death Knight Understudies.

• Add creature texts to Razuvious and Understudies. broadcast_ids are present in DB. Razuvious' "Pathetic...", picked Broadcast_ID "27865" as there are 3 exactly the same in the DB
• Only the Bottom left add can speak. Razuvious only speaks to this add. Sometimes he doesn't speak, but emotes
• Razuvious should emote "Exclamation" to all adds. Each add responds with a "Talk" and "Salute". Only the bottom left add is special. Razuvious often, but not always speaks to the bottom left add. Bottom left always speaks with 1 of 3 texts.
• Event repeats every 60-80s.
• Razuvious walks closely to the add and then emotes or speaks.
• Order of adds looks to be based on timing and wherever he is during his patrol. Implementation is ordered and based on reached WP.

Issues Addressed:

How to Test AzerothCore PRs

When a PR is ready to be tested, it will be marked as [WAITING TO BE TESTED].

You can help by testing PRs and writing your feedback here on the PR's page on GitHub. Follow the instructions here:

REMEMBER: when testing a PR that changes something generic (i.e. a part of code that handles more than one specific thing), the tester should not only check that the PR does its job (e.g. fixing spell XXX) but especially check that the PR does not cause any regression (i.e. introducing new bugs).

For example: if a PR fixes spell X by changing a part of code that handles spells X, Y, and Z, we should not only test X, but we should test Y and Z as well.

Pausing his patrol to walk up to an add is broken / incomplete and resuming pathing is broken.

I can stop him with me->SetControlled(false, UNIT_STATE_ROOT); or setting speed to 0.0f does the trick but unrooting makes him skip a waypoint...

currently relies on loading path after doing RP. This moves Razu back to wp 0 of his path. Instead, he should continue where he left off
