[Editor-Only] If the field represented by the `property` has a Animancer.DefaultValueAttribute, this method sets the `value` to its Animancer.DefaultValueAttribute.Primary value. If it was already at the value, it sets it to the Animancer.DefaultValueAttribute.Secondary value instead. And if the field has no attribute, it uses the default for the type.

public static void SetToDefault<T>(ref T value, FieldInfo field)
