f8190feef2 Python: Fix divergence in tuple/subscripted type toString 
A slightly more complicated version of the situation in
https://github.com/github/codeql/pull/2507 could cause the `toString`
calculation to diverge. Although the previous PR took tuples nested
inside tuples into account (and subscripted types cannot be nested
inside each other in our modelling), it did not account for having
this nesting be interleaved, and this is what caused the divergence.

I have not done the usual "test case first to show the problem
exists", since this would also diverge and take forever to fail. The
instance observed in `scipy` was likely caused by something akin to

```python
x = ()
while True:
    x = x[(x,)]
```

Finally, to prevent this from happening with other types, I went
through and checked each instance where the string representation of
an `ObjectInternal` might potentially contain a reference to
itself (and thus explode). I encapsulated this in a
`bounded_toString` helper predicate, and used this in all the cases
where I was able to determine that the above _could_ happen.
