Description: This speed up test_peg_generator by always disabling compiler optimizations by using -O0 by default when the test is building its own C extensions. A build not using --with-pydebug in order to speed up test execution winds up with this test taking a very long time as it would do repeated compilation of parser C code using the same optimization flags as CPython was built with. This speeds the test up 6-8x on gps-raspbian. Includes the win32 changes from #31017 by Kumar Aditya https://bugs.python.org/issue46576
