2318752c14 python: add reads of captured variables to 
type tracking and the API graph.

- In `TypeTrackerSpecific.qll` we add a jump step
  - to every scope entry definition
  - from the value of any defining `DefinitionNode`
    (In our example, the definition is the class name, `Users`,
     while the assigned value is the class definition, and it is
     the latter which receives flow in this case.)
- In `LocalSources.qll` we allow scope entry definitions as local sources.
  - This feels natural enough, as they are a local source for the value, they represent.
    It is perhaps a bit funne to see an Ssa variable here,
    rather than a control flow node.
 - This is necessary in order for type tracking to see the local flow
    from the scope entry definition.
- In `ApiGraphs.qll` we no longer restrict the result of `trackUseNode`
  to be an `ExprNode`. To keep the positive formulation, we do not
  prohibit module variable nodes. Instead we restrict to the new
  `LocalSourceNodeNotModule` which avoids those cases.
