[lldb/Process] Populate queues in Scripted Process

This patch enhances queue support in Scripted Processes.

Scripted Threads could already report their queue name if they had one,
but this information was only surfaced when getting the process and
thread status.

However, no queue was create and added to the scripted process queue
list. This patch improves that by creating a queue from the scripted
thread queue name. For now, it uses an invalid queue id, since the
scripted thread doesn't expose this capability yet, but this could
easily be supported if the queue id information is available.
