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.
