chore: Move static Player functions and internal linkage to manager class (#1412)

* 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*.

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