bpo-45115: Enable optimiaztions on Windows debug build

[vstinner]

On Windows, enable compiler optimizations on the debug build to make
tests run faster and to reduce the stack memory usage, especially
with static inline functions used in Python public header files.

The Windows GitHub Actions now build Python in debug mode to catch
more bugs.

bpo-45115: Enable optimiaztions on Windows debug build #28181

Ooops, there is a typo in the commit message. It can be fixed when the PR is merged.

I modified my PR #28128 to see if enabling compiler optimizations fix test_exceptions when Py_TYPE() macro is converted to a static inline function.

[Reference] Timing of a release build (with optimizations), from PR #28180:

• Windows x86: Total duration: 9 min 39 sec (test_asyncio.test_sendfile_close_peer_in_the_middle_of_receiving() re-run)
• Windows x64: Total duration: 9 min 9 sec

[With this PR] GitHub Action jobs with Python built in debug mode with optimizations:

• Windows x86: Total duration: 13 min 23 sec.
• Windows x64: Total duration: 10 min 30 sec (test_asyncio.test_sendfile_close_peer_in_the_middle_of_receiving() re-run).

Currently, the slowest job is the Address Sanitizer. IMO as soon as the Windows jobs are faster than the Address Sanitizer job, the little slowdown of this PR on GitHub Action is accepted. And it's way better to test Python on Windows in debug mode!

Building Python in debug mode does fix test_exceptions crash when Py_TYPE() macro is converted to a static inline function:
