KConfigSkeletonItem : allow to set a KconfigGroup to read and write items in nested groups

Summary:
Currently KConfgiSkeleton cannot manage item entry in subgroup, like

```
[General][Colors]
MyItem=foo
```

Example of use

```
// Generated Class with KConfig compiler, inherits KConfigSkeleton

KConfigGroup generalGroup( &config, "General" );
KConfigGroup colorsGroup = config.group( "Colors" )
myItem->setGroup(cg); // Now can take a KConfigGroup
addItem(myItem, "MyItem");

```

Evolution of kconfig compiler will follow to consider this.
