Fixes #8242
Description
Added option to compute Focal Loss (FL) directly from class probabilities instead of logits.
Added parameters to the different loss classes combining Dice and FL to allow choosing the activation function (if any) for FL.
Added corresponding tests passing with
pytest tests/losses/ -v.Types of changes
