Description: Summary Several tests in test_inspect, test_import, test_importlib.test_util, test_py_compile, and test_compileall assume the default __pycache__ bytecode layout and fail when the suite is run with PYTHONPYCACHEPREFIX set. Fix: neutralize sys.pycache_prefix (and PYTHONPYCACHEPREFIX for subprocess-based tests) where that assumption is made so tests are environment-independent. The key pattern for subprocess tests: assert_python_ok() runs with -I (isolated mode), which ignores PYTHONPYCACHEPREFIX, so the expected cached path must be computed with sys.pycache_prefix=None to match. Issue: gh-151626
