[debugger] Fixing two crashes while debugging an Android app. (#13373)
* [debugger] Fixing two crashes while debugging an Android app. -> Doing stepping into in VSM in some situation the frame saved in TLS is not synchronised with what is really been executed in the main thread. This makes the debugger-agent crashes because it tries to get variable info in some memory that is not available anymore. -> To fix it I forced the update of stack when CMD_THREAD_GET_FRAME_INFO is called. -> Doing step over in Visual Studio for Windows, if you have the threads debugger window enabled, VSW calls frame_commands for each thread that is showed, and if the thread is not really_suspended it tries to get variable info from a memory that is not available anymore because the thread is not suspended yet. -> To fix it I don't send variable info of a frame if the thread is not really_suspended and doesn't have an async_state valid. Cherry-picked with some light massaging by Alex Thibodeau (case 1249172)
