Taus Brock-Nannestad 11c85f0fb5 Python: Clean up various jump/local data flow steps

Removes steps from `ModuleVariableNode`s from `essaFlowStep`, and
instead puts them only in `jumpStep`. This cleans up the logic a bit.

This slightly broke the type tracker implementation (as it relied on
`essaFlowStep` being fairly liberal), so I have rewritten it to
explicitly rely on just familiar predicates for local and jump steps.

Additionally, we disallow Essa-to-Essa steps where exactly one of the
two nodes corresponds to a global variable (i.e. only local-local and
global-global steps).
