cdf4dd16f0 Python: Fix module level flow for iterable unpacking
(and for * patterns in match)

Since `PhaseDependentFlow` uses the following predicate, that relies on
.getScope() to be present for there to be any importTimeFlow (flow at
toplevel scope), it's important that data-flow nodes implement `.getScope`.

```
private predicate isTopLevel(Node node) { node.getScope() instanceof Module }
```

By implementing getScope, we can now rely on default implementation of
`getEnclosingCallable` in DataFlow::Node:

```
  /** Gets the enclosing callable of this node. */
  DataFlowCallable getEnclosingCallable() { result = getCallableScope(this.getScope()) }
```

45bb4a0ee5 python: remove TaintStepFromSummary

5cb71ce7e5 python: remove a use of points-to
This is used by `Scope::isPublic` which in turn is called by the framework model for `setuptools`.

On my current quesry, this had a dramatic effect on the most expensive predicates:
