Disable UNT0039 in Reset methods

[sailro]

Copied from microsoft/vscode-dotnettools#2827 cc @BarionLP

Describe the feature you'd like
i have this pattern where i expose a field in the editor and use the Reset method to populate it with a default reference, e.g. like this:

[SerializeField] private MyComponent component;

void Reset()
{
    component = GetComponent<MyComponent>();
}

this way i have the option to use a different one without having to assign the field every time

unfortunately this will trigger UNT0039 telling me to use RequireComponentAttribute.
It would be nice to disable that rule in this case

Alternatives considered
people probably do other things with GetComponent in Reset so the rule could only be disabled when no members of the result are used

@BarionLP, sorry if I'm missing something, but what is the issue having something like that?

[RequireComponent(typeof(ExampleRequiredBehaviour))]
public class ExampleBehaviour : MonoBehaviour
{
    [SerializeField]
    private ExampleRequiredBehaviour _exampleRequiredBehaviour;

    protected void Reset()
    {
        _exampleRequiredBehaviour = GetComponent<ExampleRequiredBehaviour>();
    }
}

}

ExampleBehaviour may need to exist without ExampleRequiredBehaviour on the same GameObject.
It is a rare scenario but it gives my games architecture flexibility
