    gdb: use inferior::threads instead of all_threads and a PID filter
    
    I noticed a few places where we iterated over `all_threads ()` but
    then immediately filtered by PID.  It would be better to instead
    iterate over `inferior::threads ()` and remove the PID filtering.
    
    These should be equivalent as a single inferior should contain every
    thread with a given PID, and should only contain threads with that
    given PID.
    
    While editing the `for (...)` loops I have replaced 'auto' with
    'thread_info' for additional type clarity.
    
    There should be no user visible changes after this commit.
