Vivek Khimani dd6d843057 [pyflakes] Recognize frozendict as a builtin for Python 3.15+ (#24100) ...

## Summary

Register `frozendict` (PEP 814) as a version-gated builtin for Python
3.15+, fixing `F821` when `target-version = "py315"`

Closes #24095

## Test plan

- `frozendict` with `target-version >= py315` → no diagnostic
- `frozendict` with `target-version < py315` → `F821` with version hint
suggesting `py315`
- Existing version-gated builtin tests still pass (e.g.
`PythonFinalizationError`, `__annotate__`)
