[lldb/crashlog] Parse thread fields and pass it to crashlog scripted process

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.
