[lldb/crashlog] Add CrashLogScriptedProcess & remove interactive mode

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.
