refactor: restructure events

[TestingPlant]

Definitions to avoid ambiguity:

• "Events" - Events from crates/hyperion/src/simulation/event.rs that are currently processed through EventQueue
• "Event code" - Code in events/, such as the tag event

Events are mostly repackaged Valence packets with some processing, which can easily be done in the event code. Custom events can also already be sent through HandlerRegistry, and keeping the separate events system adds confusion on which system to use. In addition, the EventQueue approach requires allocations and requires us to maintain RuntimeLifetime, which cannot be checked at compile time and causes aborts at runtime if used improperly while the HandlerRegistry does not require allocations to send events and can send events with references to the original packet data that is completely checked at compile time. This PR removes the events system.
