chore: Move Player ghosting functionality to GhostComponent (#1413)

* Moving and organizing Player code

- Move code to CharacterComponent
- Remove extraneous interfaces
- Simplify some code greatly
- Change some types to return and take in const ref (only structs larger than 8 bytes benefit from this change.)
- Update code to use CharacterComponent for sending to zone instead of Player*.

- Remove static storage container (static containers can be destroyed before exit/terminate handler executes)

* remove player cast

* Remove extra includes

* Add a player manager

Used for the static Player functions.  Further removes stuff from the Player class/file.

* chore: Move ghosting functionality to component

Tested that ghosting still works and players are still firing off the OnPlayerLeave and relevant handlers.

* move to unordered_set
