tweak(gamestate/server): sanitize network synchronized scene

[tens0rfl0w]

Goal of this PR

The original GTA network code includes sanitization for local player peds, but it still allows malicious actors to permanently desync a player’s ped on all remote clients. Additionally, other remotely owned entities lack any sanitization, making them vulnerable to similar abuse.

How is this PR achieving the goal

• Introduces a template-based Sanitize method for all game events, streamlining future sanitization implementations.
• Blocks all networked synchronized scenes containing entities that are not owned by the requesting client.
• Provides a bypass mechanism for specific entities via SET_ENTITY_REMOTE_SYNCED_SCENES_ALLOWED.
• Allows retrieval of the current bypass state with GET_ENTITY_REMOTE_SYNCED_SCENES_ALLOWED.

Note: Once this change reaches general availability, client-side sanitization can be removed entirely.
