gh-130524 Create WinGetpassTest class for improved coverage

[floor-licker]

Improved Getpass coverage for Windows

I followed the same pattern as the Unix tests, the new class tests the core functionality of win_getpass using msvcrt.getch for input, verifies proper handling of special characters including keyboard interrupt, ensures stream flushing works correctly, and a test for fallback_getpass() to test the mscvrt fallback mechanism when the primary method fails.

• Issue: Add more tests for getpass #130524

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

the macOS tests are failing which is odd given the @unittest.skipUnless(sys.platform.startswith("win"), "requires Windows") outer-decorator of the class. Let me try something else.

@floor-licker
before sending changes you can try to run tests using next command (I assume you are using Windows):

./python Lib/test/test_getpass.py

and also please don't forget to add news entry file (using blurb) at least when ci requires it, they should be passed.

you can read the errors in the github actions logs, everything is described there (you just don't define the objects you use)

BTW, please do not force-push; it makes reviewing harder. Moreover, all commits are squashed upon merge anyway, so there's no need for the PR/branch to be cluttered with amendment commits. See also the devguide.

@donBarbos my apologies for the mess, just lost access to my windows machine so I've been trying to sort this out on macOS. I'll create a partition and come up with a fix. Thanks for the info, I'll give it a read.

It seems that the CI is failing because the test hangs. I'm converting it to a draft until the CI is green again.

The tests still don't seem to work. Are you willing to continue working on this @floor-licker or should someone else take over (I can't because I don't have a Windows for that; maybe @donBarbos could as it's blocking #130496).
