Add an is<PropertyName>Immutable to know if a property is immutable

Summary:
Add a utility function is<Parameter>Immutable to access immutability quickly.
Generated classes uses them internally to avoid code redundance.

Sample:
```
    /**
      Set blocked-by-default
    */
    void setBlockedByDefault( bool v )
    {
      if (v != mBlockedByDefault && !isBlockedByDefaultImmutable() )  {
        mBlockedByDefault = v;
        Q_EMIT blockedByDefaultChanged();
      }
    }

    /**
      Is blocked-by-default Immutable
    */
    bool isBlockedByDefaultImmutable()
    {
      return isImmutable( QStringLiteral( "blockedByDefault" ) );
    }
```

```
    /**
      Set org.kde.ActivityManager.ResourceScoringEnabled
    */
    void setResourceScoringEnabled( bool v )
    {
      if (!isResourceScoringEnabledImmutable() )
        mResourceScoringEnabled = v;
    }

    /**
      Is org.kde.ActivityManager.ResourceScoringEnabled Immutable
    */
    bool isResourceScoringEnabledImmutable()
    {
      return isImmutable( QStringLiteral( "resourceScoringEnabled" ) );
    }
```
