This adds a new read-only attribute gdb.InferiorThread.details, this attribute contains a string, the results of target_extra_thread_info for the thread, or None, if target_extra_thread_info returns nullptr. As the string returned by target_extra_thread_info is unstructured, this attribute is only really useful for echoing straight through to the user, but, if a user wants to write a command that displays the same, or a similar 'Thread Id' to the one seen in 'info threads', then they need access to this string. Given that the string produced by target_extra_thread_info varies by target, there's only minimal testing of this attribute, I check that the attribute can be accessed, and that the return value is either None, or a string.
