gh-58933: Make pdb return to caller frame correctly when f_trace is not set

[gaogaotiantian]

For commands like next, return, until on a return event, if f_trace of the previous frame is not set, the command will not stop at the previous frame. A similar issue is fixed for step, we are generalizing that fix to commands other than continue.

• Issue: trace function not set, causing some Pdb commands to fail #58933

Hi @iritkatriel , this is a bug fix (a rather important one I think) and maybe it should be backported?

Sorry, @gaogaotiantian and @iritkatriel, I could not cleanly backport this to 3.12 due to a conflict.
Please backport using cherry_picker on command line.

As main is 3.14 now, we should probably need to backport to 3.13 too?

[gaogaotiantian]

And I'll work on the cherry pick.
