USP0007 Don't flag fields with SerializeField or SerializeReference attributes as never assigned

Fields with the SerializeField or SerializeReference attributes should not be marked as unassigned.

Suppressed Diagnostic ID

CS0649 - Field is never assigned to, and will always be null

Examples of code that produces a suppressed diagnostic

using UnityEngine;

class Camera : MonoBehaviour
{
	[SerializeField]
	private string someField;
}

Why is the diagnostic reported?

The compiler detected an uninitialized private field declaration that is never assigned a value.

Why do we suppress this diagnostic?

A field with the SerializeField or SerializeReference attributes are exposed to Unity and can be assigned in the Unity Inspector.
