This patch introduces the `ScriptedThread` class with its python interface. When used with `ScriptedProcess`, `ScriptedThreaad` can provide various information such as the thread state, stop reason or even its register context. This can be used to reconstruct the program stack frames using lldb's unwinder. rdar://74503836 Differential Revision: https://reviews.llvm.org/D107585 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com>
