**Add "View Output Layers" option for model child algorithms **

PR Description:

When editing a model through the designer (and after having run that model), you can now right click any child step in the model
and select "View Output Layers". This will add the output layers from that step as new layers in the current QGIS project.

This action is available for ALL child algorithms in the model, even if the model is not configured to use the outputs from those
children as model outputs.

This is designed as a helpful debugging action. If a user's model fails (or gives unexpected results), they can then trace through
the model and view the outputs for suspected problematic steps. It avoids the need to add temporary outputs to a model and re-run to test.

Additionally, this action is always available after running the model, EVEN if the model itself failed (eg because of a misconfigured
step later in the model).

Now also contains a "View Log" action, so that you can see the log for each child after you've closed down the algorithm dialog:
