pipeline: rpi: Handler controls::rpi::ScalerCrops

Handle multiple scaler crops being set through the rpi::ScalerCrops control. We now populate the cropParams_ map in the loop where we handle the output stream configuration items. The key of this map is the index of the stream configuration structure set by the application. This will also be the same index used to specify the crop rectangles through the ScalerCrops control. CameraData::applyScalerCrop() has been adapted to look at either controls::ScalerCrop or controls::rpi::ScalerCrops. The latter takes priority over the former. If only controls::ScalerCrop is provided, the pipeline handler will apply the same scaler crop to all output streams. Finally return all crops through the same ScalerCrops control via request metadata. The first configure stream's crop rectangle is also returned via the ScalerCrop control in the request metadata.
