    gdb, multi-target: pass a target argument to delete_exited_threads
    
    Similar to the parent commit, delete_exited_threads is also mostly
    used in the context of a particular target.  Pass that target as a
    parameter and skip other targets.
    
    There seems to be two cases where we actually would want to iterate
    all targets.  One use is in inferior_appeared (inferior.c) and the
    other is in thread_select (thread.c).  To handle these cases, allow
    the argument to be nullptr.
