Returns True if our sys.executable interpreter requires environment
variables in order to be able to run at all.
This is designed to be used with @unittest.skipIf() to annotate tests
that need to use an assert_python*() function to launch an isolated
mode (-I) or no environment mode (-E) sub-interpreter process.
A normal build & test does not run into this situation but it can happen
when trying to run the standard library test suite from an interpreter that
doesn't have an obvious home with Python's current home finding logic.
Setting PYTHONHOME is one way to get most of the testsuite to run in that
situation. PYTHONPATH or PYTHONUSERSITE are other common environment
variables that might impact whether or not the interpreter can start.

Assert that running the interpreter with `args` and optional environment
variables `env_vars` succeeds (rc == 0) and return a (return code, stdout,
stderr) tuple.
If the __cleanenv keyword is set, env_vars is used as a fresh environment.
Python is started in isolated mode (command line option -I),
except if the __isolated keyword is set to False.
