  • Add _PYTHON_SUBPROCESS_USE_POSIX_SPAWN environment knob

Add support for disabling the use of posix_spawn via a variable in
the process environment.

While it was previously possible to toggle this by modifying the value
of subprocess._USE_POSIX_SPAWN, this required either patching CPython
or modifying it within the interpreter instance which is not always
possible, such as when running applications or scripts not under a
user's control.
