feat(Core/World): implement Sun's Reach Reclamation Event and Phasing

[sogladev]

Changes Proposed:

This PR proposes changes to:

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

This builds and I included the data from Bench. It can do phase handling, but data is incomplete. Phases activate game_events. Each phase needs to have spawns/gobjects/quests set. When compared to cmangos, handlings looks OK but data is incomplete. Though cmangos isn't working prefectly either, like the anvil progression is missing, but spawns are much better.

As for style, init world states is ugly. Not sure what it does, dialog % when talking to the guy next to the island portal in Shat.

Issues Addressed:

• Closes

SOURCE:

The changes have been validated through:

• Live research (checked on live servers, e.g Classic WotLK, Retail, etc.)
• Sniffs (remember to share them with the open source community!)
• Video evidence, knowledge databases or other public sources (e.g forums, Wowhead, etc.)
• The changes promoted by this pull request come partially or entirely from another project (cherry-pick). Cherry-picks must be committed using the proper --author tag in order to be accepted, thus crediting the original authors, unless otherwise unable to be found

Tests Performed:

This PR has been:

• Tested in-game by the author.
• Tested in-game by other community members/someone else other than the author/has been live on production servers.
• This pull request requires further testing and may have edge cases to be tested.

Commands:
.worldstate sunsreach phase print phase info (phase, subphase, counters)
.worldstate sunsreach phase 1 sets phase to [0-4] setting 4->1 is valid
.worldstate sunsreach subphase print phase info (phase, subphase, counters)
.worldstate sunsreach subphase 1 Sets subphase mask; e.g., 0x3 sets 0x2 (anvil) and 0x1 (portal). Maybe reversable, didn't work when I tried
.worldstate sunsreach counter print phase info (phase, subphase, counters)
.worldstate sunsreach counter 999 sets counter, quest completions increase counter, once a value is reached (worldconfig), transitions to next phase/subphase

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:

http://www.azerothcore.org/wiki/How-to-test-a-PR

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.
