gh-124102: Update internal documentation under PCbuild, so it now correctly states that Windows Dependency Information

[Wulian233]

In https://docs.python.org/3.14/using/configure.html.
Visual Studio 2017 or later is required, actually currently VS2015 is the minimum version.

VS2015 was EOL in 2020 October

https://learn.microsoft.com/lifecycle/products/visual-studio-2015

So I removed VS2015 and earlier version support

Before this change, the description in python.props stated:
https://github.com/python/cpython/blob/main/PCbuild/python.props#L8-L10

Use the latest available version of Visual Studio to build. To override
this and build with an earlier version, pass "/p:PlatformToolset=v100"
(for example) when building.

However, v100 corresponds to Visual Studio 2010, and now Visual Studio 2017 or later is required. v100 is no longer available. See https://docs.python.org/3.14/using/configure.html.

Currently, the latest Visual Studio 2022 uses v143. Therefore, I have changed it to the officially supported Visual Studio 2017 (v141). See https://github.com/python/cpython/blob/main/PCbuild/readme.txt#L62.

To correctly build CPython, the minimum Python required version is now 3.10; otherwise, it will download via NuGet online. See https://github.com/python/cpython/blob/main/PCbuild/find_python.bat#L45

However, descriptions in other files are outdated, mentioning versions like 3.6, 2.7, and 3.4. Due to the long time lapse, these descriptions have become inconsistent across files. I have now standardized them

News entry needed. (I would also want it to merge.)

[Wulian233]

No problem (Before I thought only changing the readme and syncing information not required NEWS😥)

I have finished NEWS, in addition, I made env.bat support VS2017 and above version detection

Hello @zooba , thank you for your review. I have made the changes, could you please review again? Thank you!

(I think I made some additional changes at the time, do you think these should be changed? I am considering revert the changes made to these two files)

Tools/c-analyzer/distutils/cygwinccompiler.py
Tools/c-analyzer/distutils/_msvccompiler.py

[zooba]

Yeah, revert the Tools directory changes and we're good to go (we explicitly aren't maintaining distutils anymore, including the copy used for tests, at least until the tests start breaking).
