feat(server)!: Vehicle Spawning Overhaul

[Manason]

Description

• deprecating QB callbacks for creating/spawning vehicle in favor of new ox_lib callbacks
• deprecating vehicle creation functions/callbacks on the server which use CreateVehicle native rather than CreateVehicleServerSetter. Existing functions/callbacks are now wrappers.
• BREAKING CHANGE: 'QBCore:Server:CreateVehicle' server callback will now return nil rather than 0 if the server artifact is below 5904. This brings the behavior in-line with the function version.
• server events/functions which spawn vehicle refactored to call the server to spawn the vehicle
• BREAKING CHANGE: QBCore.Functions.CreateVehicle server function now returning the netId instead of the entityId. I'm too sure about whether this is a good change or not, but it seemed odd that the original callback returned the netId and the function returned the entityId, so I picked one and went with it.

Unrelated: I don't understand why the createVehicle function is spawning and deleting a temp vehicle.
Unrelated: Seems like the callback for spawning vehicles should live right next to the server function for spawning vehicles rather than have it in the 'events' file.
