returnn Add tensorboard to torch engine

This adds tensorboard support to the torch engine. right now, it just uses the default directory name "runs" to dump the data to. also, it just dumps all scores from eval_info into the tensorbard. since we might want to discuss these two decisions, i marked this as a draft request.

Note: You can rebase to master now. That should fix the CI issues. (But despite that, see also my other comment.)

The diff is still huge and contains things already in master, maybe not rebase but merge master again.

Again (the unrelated) #1770... I will look into that.

Can you rebase to current master (or merge with master)? That should hopefully fix the CI issues.

~Yes there are still unresolved issues, see above: https://github.com/rwth-i6/returnn/pull/1704/files#r2375662908~

Ah, sorry, this is already resolved. We can merge.
