Copilot f077e7c27c Python: add CFG-binding gap tests (red)
Adds inline-expectation tests for the new shared CFG implementation in
python/ql/lib/semmle/python/controlflow/internal/AstNodeImpl.qll,
covering every Python binding construct that introduces a variable.

The test files use MISSING: annotations to record bindings whose
defining Name AST node is *not* currently reachable from the new CFG.
These are the 'red' half of red-green commit pairs: subsequent commits
will extend AstNodeImpl to cover each construct and remove the
corresponding MISSING: marker.

Confirmed-broken categories:
- Import aliases (from x import a)
- Annotated assignment (x: int = 1)
- Exception handler (except E as e)
- Match patterns (case x, case [a,b], case ... as v)
- PEP 695 type params (def f[T], class C[T])

Confirmed-working (no MISSING:):
- Compound targets, with-as, comprehensions, decorated def/class,
  walrus, starred.
