gh-104372: Cleanup _posixsubprocess make_inheritable for async signal safety

[gpshead]

We move all of the Python C API calls into the parent process up front instead of doing PyLong_AsLong and PyErr_Occurred and PyTuple_GET* from the post-fork/vfork child process.

Much of this was long overdue. We shouldn't have been using PyTuple and PyLong APIs within all of the lower level functions anyways.

• Issue: subprocess can block all Python threads when using vfork() until the child process exec() succeeds or fails. #104372

[gpshead]

This is a code cleanup that #104515 mentions as desirable so that a nicer PR can be made for the larger issue.
