fix(Core/Movement): (#7008)

- Get zone/area IDs from vmap data in the liquid update
- Add new method Map::getFullVMapDataForPosition to get area info and liquid info in a single vmap lookup
- Adjust GetZoneId/GetAreaId on WorldObject to always return these cached fields.
- Clean up liquid state handling on Unit and Player
- Implemented getting area id from gameobject spawns.
- Removed old core related to getting movement flags dependent on environment.
- Movement flags are now processed more precisely and dynamically.

Original source: TrinityCore.

- Closes #5086
- Updates #2208.
