LLDB already had a lot of the plumbing needed to step back, this PR adds a step back command making use of this existing infrastructure. The way this is implemented is by giving `ThreadPlanStepInstruction` a direction parameter, if the step back instruction command is used a thread plan with `eForwardReverse` is pushed. Of course stepping back does not work for any target, it needs to support reverse execution (`SupportsReverseDirection`), this is the case for some remote GDB targets.
