[3.11] gh-110036: multiprocessing Popen.terminate() catches PermissionError (GH-110037) (#110065)

gh-110036: multiprocessing Popen.terminate() catches PermissionError (GH-110037)

On Windows, multiprocessing Popen.terminate() now catchs
PermissionError and get the process exit code. If the process is
still running, raise again the PermissionError. Otherwise, the
process terminated as expected: store its exit code.
