sijun-yang c3bfefaeb0 Remove private comprehension flags (#8537) ...

* Remove the private assignment-expression marker

Why:
extend_namedexpr_scope() already propagates assignment-expression
targets and records DEF_GLOBAL or DEF_NONLOCAL in comprehension scopes.
ASSIGNED_IN_COMPREHENSION remained only for conflict checks. Its private
bit overlaps CPython's packed LOCAL scope bit.

Changes:
- Register assignment-expression targets as ordinary assignments.
- Detect later target conflicts from existing declaration flags.

* Remove the private comprehension iterator flag

Why:
ITER duplicates the DEF_LOCAL and DEF_COMP_ITER facts already recorded
for comprehension targets. Its private bit also overlaps CPython's
packed scope field.

Changes:
- Use those flags for rebinding checks and local restoration around
  inlined comprehensions.

* Preserve source names in named-expression diagnostics

Why:
Assignment-expression diagnostics exposed the mangled keys used for
symbol-table lookup. CPython reports identifiers as written in source.

Changes:
- Use source names in both comprehension conflict diagnostics.
- Enable test_named_expression_invalid_mangled_class_variables.
