fix(code-runtime-python): stop the program's compile from inheriting the module's future annotations

Browse Source 
bootstrap.py imports from __future__ import annotations; compile(wrapped) was
inheriting that PEP 563 flag, stringifying the program's type annotations and
changing the semantics of a legal program that reads f.__annotations__ at
runtime. compile(..., dont_inherit=True) stops the leak; a regression test
defines an annotated function and asserts the annotation is the live int class,
verified fail-before by removing dont_inherit (the test turns red).
