About the PR

Rewrote the changeling identity networking to work a new datatype instead of a dictionary.
Made changelings unable to devour a body that has been recently devoured by another changeling (or themselves).

Open as draft because this is very reviewable, just need to clean up, add docs and add an objective using the new API.

Why / Balance

Allows for easier keeping track of unique identities and similiar without needing to track several seperate lists.

Technical details

New ChangelingIdentityData. We manually network it from Server to Client with the relevant information regarding an identity.
Then all checks are just made using that via previous or new API.

Requirements

• I have read and am following the Pull Request and Changelog Guidelines.
• I have added media to this PR or it does not require an in-game showcase.

Breaking changes

ChangelingIdentityComponent no longer raises AfterAutoHandleStateEvent on itself. The functionality has been moved to a ComponentHandleState subscription. This also means the component is manually networked.
ChangelingIdentityComponent.ConsumedIdentities now uses a new data definition ChangelingIdentityData instead of Dictionary<EntityUid, EntityUid?>. Specific items can be retrieved using the new API.
