Python: visit function parameter and return annotations in new CFG

The new (shared-CFG-based) Python control flow graph in
`semmle.python.controlflow.internal.Cfg` previously did not emit CFG
nodes for parameter type annotations (`def f(x: T): ...`) or for the
return type annotation (`-> T`). The legacy CFG emitted both, and a
small number of framework models rely on this: `LocalSources.qll`'s
`annotatedInstance` walks the parameter annotation expression by way
of its CFG node to track that a parameter receives an instance of the
annotated class.

After the dataflow flip to the new CFG/SSA this regression manifested
as lost flows in any test exercising annotation-based parameter
tracking: FastAPI `Depends()` receivers, Pydantic request bodies,
Starlette `WebSocket`, the call-graph type-annotation test, and so on.
Extend `FunctionDefExpr` to visit each annotation as a child of the
function-def expression, in CPython evaluation order: positional
parameter annotations, `*args` annotation, keyword-only parameter
annotations, `**kwargs` annotation, then the return annotation. (Lambda
expressions have no annotations in Python syntax, so `LambdaExpr` is
unchanged.) PEP 695 type parameters remain out of scope; they belong
to the inner annotation scope, not the enclosing CFG.

Restored test results across `framework/aiohttp`, `framework/fastapi`,
`framework/lxml`, the `CallGraph-type-annotations` test, and
`CWE-022-PathInjection`. Two FastAPI list-comprehension MISSING markers
become positive (`taint_test.py:41,55`). CPython CFG consistency
remains clean.

-* Models-as-data flow summaries now use fully qualified field names (for example, `MyNamespace::MyStruct::myField`) instead of unqualified field names such as `myField`. We recommend updating existing flow summaries to use fully qualified field names. Unqualified field names are still supported, but that support will be removed in a future release.

This restores annotation-based type tracking through framework models such as FastAPI's `Depends()`, Pydantic request models, Starlette `WebSocket` handlers, and any other models that flow a class reference through `Parameter.getAnnotation()` to identify instances of the annotated class.
