This patch subtracts 1 to the pc of any frame above frame 0 to get the
previous line entry and display the right line in the debugger.
This also rephrase some old comment from `48d157dd4`.

Previously, the ScriptedThread used the thread index as the thread id.
This patch parses the crashlog json to extract the actual thread "id" value,
and passes this information to the Crashlog ScriptedProcess blueprint,
to create a higher fidelity ScriptedThreaad.
It also updates the blueprint to show the thread name and thread queue.
Finally, this patch updates the interactive crashlog test to reflect
these changes.

This patch pipes down the `-a|--load-all` crashlog command option to the
Scripted Process initializer to load all the images used by crashed
process instead of only loading the images related to the crashed
thread.
This allows us to recreate artificial frames also for the non-crashed
scripted threads.

This patch introduces a new type of ScriptedProcess: CrashLogScriptedProcess.
It takes advantage of lldb's crashlog parsers and Scripted Processes to
reconstruct a static debugging session with symbolicated stackframes, instead
of just dumping out everything in the user's terminal.
The crashlog command also has an interactive mode that only provide a
very limited experience. This is why this patch removes all the logic
for this interactive mode and creates CrashLogScriptedProcess instead.
This will fetch and load all the libraries that were used by the crashed
thread and re-create all the frames artificially.
