What does this PR do?

This change switches from the deprecated begin_forward/end_forward to plan.

This change doesn't switch forward to run yet, since it requires that we have access to the softmax scale and the logit softcap outside the model.

It is already set by the context manager:

window_left=-1 if window_left is None else window_left,

window_left=-1 if window_left is None else window_left,

This is one of the arguments that is gone in the new run() API.
