Second batch of test reblessings, capturing changes in result content
(not just toString labels):
- Framework taint/concept tests (fastapi, sqlalchemy, aiohttp, lxml,
stdlib, django-orm): mostly gained MISSING-tainted annotations where
the new dataflow no longer reaches sinks. Some are real taint
regressions; left as documented failures for follow-up.
- Exception-handler tests (CWE-209-StackTraceExposure, EmptyExcept,
CatchingBaseException, IncorrectExceptOrder, FileNotAlwaysClosed,
FindSubclass/Find, Statements/exit/UseOfExit): the no-raise shared CFG
abstraction does not emit ExceptionSuccessor abrupt-completion edges
from arbitrary expressions, so except-handler bodies (and their
exception target Names) are statically dead. Tracked separately under
cfg-modelling-exceptions.
- Dataflow-path / control-flow node toString polish across the security
query suite (PathInjection, CodeInjection, UnsafeUnpacking,
UnsafeUsageOfClientSideEncryptionVersion, RequestWithoutValidation,
ReflectedXss, CallGraph): simple-leaf nodes now stringify as their
AST text instead of 'After X'.
- SSA / call-graph improvements (CmpTest, CallGraph/InlineCallGraphTest):
fewer SSA mismatches between new and old; two previously-MISSING tt=
annotations resolved.

After the shared-CFG migration, DataFlow::Node.asCfgNode() returns
Cfg::ControlFlowNode rather than the legacy Flow::ControlFlowNode, and
funcValue.getACall() / dfCall.getNode() now return different CFG types
(legacy vs new). Update the two remaining test queries that still cast
to legacy NameNode/CallNode types to bridge through Cfg:: types or AST.
* experimental/import-resolution-namespace-relative/test.ql: cast to
Cfg::NameNode instead of legacy NameNode.
* experimental/library-tests/CallGraph/InlineCallGraphTest.ql: change
predicate signatures from CallNode to AST Call, and bridge to
legacy CallNode (points-to) and Cfg::CallNode (type-tracking)
via getNode() on each side.

Also fixes an issue with the return type annotations that caused these
to not work properly.
Currently, annotated assignments don't work properly, due to the fact
that our flow relation doesn't consider flow going to the "type" part of
an annotated assignment. This means that in `x : Foo`, we do correctly
note that `x` is annotated with `Foo`, but we have no idea what `Foo`
is, since it has no incoming flow.
To fix this we should probably just extend the flow relation, but this
may need to be done with some care, so I have left it as future work.
In reality, we only want to model this as a `rest_framework.response.Response`, since our .qll modeling is more precise for rest-framework responses than if we also modeled it as a basic django http response. (specifically, that default mime-type handling is way different).
I fixed it in both predicates... I think we might still be able to remove
`newDirectAlias` -- but with it being better, it will allow us to better test if `newImportAlias` actually cover everything we need!
Due to the 'only model most specific spec' logic highlighted in previous
commit, I'm changing away from MethodView/View, and use Django view instead.
In practice this shouldn't matter at all, but for writing tests it would
have been a nice fix to only have the "same name but more specific"
logic apply when it's the same _definition_ location. We used to have
this information available, but right now we don't... so instead of
spending a lot of time rewriting the core library, I simply used a
different class :D :O :(
- `--max-import-depth=3` to give points-to a chance
- `not_root` dir to force namespace package logic
- add usage in `example.py` to get files extracted
