c386f4a009 Python: Clean up py/insecure-protocol
Going all the way to the AST layer seemed excessive to me, so I rewrote
it to do most of the logic at the data-flow layer. In principle this
_could_ result in more names being computed (due to splitting), but in
practice I don't expect this make a big difference.

a55b43b67e Python: Use LocalSourceNode throughout step
This commit does a lot of stuff all at once, so here are the main
highlights:

In `TypeTracker.qll`, we change `StepSummary::step` to step only between
source nodes. Because reads and writes of global variables happen in two
different (jump) steps, this requires the intermediate
`ModuleVariableNode` to _also_ be a `LocalSourceNode`, and we therefore
modify the charpred for that class accordingly. (This also means
changing a few of the tests to account for these new source nodes.)

In addition, we change `TypeTracker::step` to likewise step between
local source nodes.

Next, to enable the use of the `track` convenience method on nodes, we
add some pragmas to `TypeTracker::step` that prevent bad joins from
occurring. With this, we can eliminate all of the manual type tracker
join predicates.

Next, we observe that because `StepSummary::step` now uses `flowsTo`, it
automatically encapsulates all local-flow steps. In particular this
means we do not have to use `typePreservingStep` in `smallstep`, but can
use `jumpStep` directly. A similar observation applies to
`TypeTracker::smallstep`.

Having done this, we no longer need `typePreservingStep`, so we get rid
of it.
