[Generator] Generator should not allow to use attrs that contradict each other.

This is an enhancement, at the moment we can do:
```csharp
[NotTvV
[TV (14,0)]
[Native]
public enum INSetSeatSettingsInCarIntentResponseCode : long {
...
}
```

We do have attrs that are pairs, one contradicting the other (NoiOS, iOS, Mac, NoMac etc..). In the case a developer makes the mistake of adding both, the generator should raise an error.
